Q: Return type declarations? With named arguments, you can now pass an argument to a function based on the parameter name. According to Will Hudgins, the author of this RFC, “The str_starts_with and str_ends_with functionality is so commonly needed that many major PHP frameworks support it, including Symfony, Laravel, Yii, FuelPHP, and Phalcon.”. A: Just like the Parameter Type Declaration, … This page is a spot to list and discuss ideas for PHP 8. Because they are enforced, type information is less likely to become outdated or miss edge-cases. This means, all strings which currently emit the E_NOTICE “A non well formed numeric value encountered” will be reclassified into the E_WARNING “A non-numeric value encountered” except if the leading-numeric string contained only trailing whitespace. It is not possible to implement an efficient weak map on top of PHP weak references because the ability to register a destruction callback is not provided.”. Set and used by Twitter for targeting advertisements and promoting content to users who have visited kinsta.com. Problem is, both ... str_starts_with () and str_ends_with () get_debug_type. PHP is an interpreted language. The new function works in quite a similar way as the gettype function, but get_debug_type returns native type names and resolves class names. PHP 7.4 added support for weak references as a way to retain a reference to an object that doesn’t prevent the object itself from being destroyed. In this blog, we look at some of these notable features and improvements in PHP 8, including the JIT compiler and the syntactical improvements that developers are sure to love. Most of these new features look like syntactic sugar. Auth0. If you've set preferences (which cookies you accept and which you don't) we store your preferences here to make sure we don't load anything that you didn't agree to. Anyway, there’s not a particular relation between parent and child class constructors. These are set for members of the Kinsta website only - members of our staff. This new major update brings a whole bunch of optimizations and powerful features to the language and we are excited to drive you through the most interesting changes that will allow us to write better code and build more powerful applications. Throw an Error exception for array, resource and object operands. According to Nikita: Usually, we say that methods always have to be compatible with the parent method. Efficiency 8. Higher conversions, better rankings & SEO, more sales. Join Zend Product Manager and Principal Engineer, Matthew Weier O’Phinney, as he discusses how new features, improvements, and deprecations in PHP 8 will impact development teams as they adopt this latest PHP version. Let me know in the comments below what new features you're most excited about and if you plan to upgrade right out of the gate. The example below from the RFC is self-explanatory: Named argument are order-independent. Another relatively minor but useful addition, the Stringable interface allows you … The early tests show that JIT would make CPU-intensive workloads run significantly faster, however, the RFC warns: “… like the previous attempts – it currently doesn’t seem to significantly improve real-life apps like WordPress (with opcache.jit=1235 326 req/sec vs 315 req/sec). ⁠⁠⁠⁠Do you want to receive a desktop notification when new content is published? One of the most promising features coming to PHP 8 is Just-in-time (JIT) compilation. PHP 8 introduces us to two different JIT engines. That’s a good improvement for the language, as gettype() is not useful for type checking. Now, this RFC proposes the introduction of a new function allowing to search inside a string: str_contains. Remove all bad practice syntax sugar / structural sugar compatibility from the 1950s such as endif, see how wordpress devs code syntax shift is all over the place and often in same file, etc etc for just { }, But this is too way too much to ask, soo, I might give the lang another look @ php v10.x. You can try out pre-release copies of PHP 8.0 today on Platform.sh, with just a one-line change. Whether you’re just starting to use WordPress or are a seasoned developer you'll find useful tips to speed up your site in this guide. If you're interested in an easy-to-use solution for adding authentication and authorization to your PHP application, be sure to sign up for a free Auth0 account to get started. PHP JIT is almost independent of OPcache and is introduced to bring significant improvements to language performance. Match … For a closer view at Named Arguments, with constraints, backward incompatibilities and several examples, see the Named Arguments RFC. Read more about backward incompatibilities in the RFC. That’s why this RFC introduces a WeakMap class to create objects to be used as weak map keys that can be destroyed and removed from the weak map if there aren’t any further references to the key object. Otherwise, convert the number to string and use a string comparison. This pseudo-type allows you to declare a value of any type without excluding type information altogether. This syntax is not particularly usable, especially in classes with a good number of properties and more descriptive names. As the official release date (26th November 2020) of PHP’s latest and greatest version PHP 8 is approaching, let’s take a look at every new feature and improvement that the PHP team has managed to fit in this version.. To understand the difference between the two control structures, consider the following switch example from the RFC: We can now get the same result as the code above with the following match expression: A big advantage of using the new match expression is that while switch compares values loosely (==) potentially leading to unexpected results, with match the comparison is an identity check (===). Weak Map class. The RFC provides two useful examples to better understand the difference between the new get_debug_type() function and gettype(). This doesn't affect the minimum required version, which is currently PHP 5.6.2. In previous PHP versions, when making a non-strict comparison between strings and numbers, PHP first casts the string to a number, then performs the comparison between integers or floats. And, there is one thing users want to see in PHP 8 is to have more real-time features. And the various cases which currently emit an E_WARNING will be promoted to TypeErrors. In PHP 8, the code above throws the following error: In PHP, throw is a statement, so it’s not possible to use it in places where only an expression is allowed. In the words of Nikita Popov. In this RFC, Nikita Popov shows how unreasonable that behavior could be with a simple example: Nikita explains how applying an arithmetic or bitwise operator to arrays, resources, or non-overloaded objects led to different results: With PHP 8 things change and the behavior is the same for all arithmetic and bitwise operators: Throw a TypeError exception for array, resource and object operands. If a class is implementing an interface, incompatible method signatures throw a fatal error. Anyway, the behavior was sometimes inconsistent. Scout APM is PHP application performance monitoring designed for developers. The main features – In my free time you can usually find me reading, hanging out with my dogs, or curling in the squat rack. PHP 8 now introduces trailing commas in parameter lists with functions, methods, and closures, as shown in the following example: In order to fetch the name of a class, we can use the Foo\Bar::class syntax. Named arguments are another new addition to PHP 8. These new functions check if a given string starts or ends with another string: Both functions return false if $needle is longer than $haystack. PHP 8 is here! If you're curious about the process of supporting PHP 8 in Symfony, be sure to check out this video where Nikita Popov of JetBrains interviews Nikolas Grekas, Symfony's principal engineer. Thanks to them, we could now avoid using sub-optimal and less intuitive functions like substr, strpos. The following example from the RFC makes it clear: If you are a WordPress developer, please note that at the time of this writing, named arguments may lead to backward compatibility issues. a hierarchical representation of the structure of source code, How to Improve PHP Memory Limit in WordPress. Flexibility 11. This prevents us to get an error if the position of the needle is 0: “This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. When enabled, native code of PHP files is stored in an additional region of the OPcache shared memory and op_array→opcodes[].handler(s) keep pointers to the entry points of JIT-ed code.”. The long-anticipated GA release of PHP 8.0 is scheduled for November 26th, 2020. WordPress sets a couple of cookies that track logged in users and store user preferences set in their WordPress user profile. This is a roundup of all the features that I’ve covered previously on this blog under a single article. Check out our plans. For the love of god it’s time to move away from $ I love taking a deep dive into hard-to-understand concepts and creating content that makes them easier to grasp. The Laravel team completed all updates needed for PHP 8 support well ahead of time. To better understand what JIT is for PHP, let’s take a quick look at how PHP executes from the source code to the final result. PHP is an interpreted language, and there have been several tactics used to improve PHP performance in the past. Here is the current support status of some popular projects, frameworks, applications, and more. This may result in wasting CPU resources and additional time. Silently convert a resource operand to the resource ID as an integer. PHP 8 Support. The following image shows a visual representation of the basic PHP execution process. Preloading provides a way to store a specified set of scripts into OPcache memory “before any application code is run“, but it doesn’t bring tangible performance improvement for typical web-based applications. Want to understand how PHP works under the hood, and how PHP 8 can make your code faster in just the nick of time? See the following code from the RFC: In PHP 7.4, the code above would simply throw a warning: Now, this RFC proposes to always throw a fatal error for incompatible method signatures. Since PHP bytecodes are stored in shared memory, they are immediately available as low-level intermediate representation and can be executed on the Zend VM right away. int $myNumber = 4; // really? Stay tuned for the next installment. According to the JIT RFC, the just in time compiler implementation should improve PHP performance. In PHP 8, these special union types have been extended to include several combinations, with a few exceptions. The match expression introduced in PHP 8 is similar to the switch statement, but with a few improvements: ‍ Note: match is now a reserved keyword. Turbocharge your website and get 24/7 support from our veteran WordPress team. Powered by the Auth0 Community. Check out our plans. str_contains () , str_starts_with () , str_ends_with () fdiv () get_debug_type () get_resource_id () token_get_all () … The property declaration is transformed as we’d explicitly declared those properties and we can use the Reflection API to introspect property definitions before the execution (see Desugaring): Reflection (and other introspection mechanisms) will observe the state after desugaring. PHP's official website claims that it is giving 3 times more performance in synthetic benchmarking and 1.5 to 2 times more performance in long-running applications. PHP 8 is pretty easy to support." So, thanks to str_contains, we can write the following code: Which is more readable and less prone to errors (see this code in action here). However, PHP 8.0 is a major version update with a large number of changes that break backwards compatibility, and many features that were deprecated within the PHP 7.x feature releases have been officially removed. Used by Facebook for targeting advertisements and promoting content to users who have visited kinsta.com. Error Reporting 13. Let's break down what attributes are and how you can use them in your code. Set and used by Google. PHP 7.4 comes with a remarkable amount of new features. Both functions are case sensitive: This RFC has been approved with 51 to 4 votes. Support for PHP 7.2 will also end at the end of 2020. Bypassing compilation, it’d be able to bring considerable improvements in performance and memory usage. Stop being affraid of introducing breaking changes at major version changes. We don’t have any limitations in using inheritance in conjunction with promoted parameters. The parameter must be an identifier and the following syntax is not allowed: According to Nikita Popov, the author of this RFC, named arguments offer several advantages. “Traits support the use of abstract methods in order to impose requirements upon the exhibiting class.”. The match expression may also contain multiple comma-separated expressions allowing for more concise syntax (source): For additional examples and cases of use, see the Match expression v2 RFC and the PHP documentation. As of PHP 5.5, the Zend OPcache extention is available by default and you can check if you have it correctly configured by simply calling phpinfo() from a script on your server or checking out your php.ini file (see OPcache configuration settings). Is your WordPress site slow? Set and used by G2 for targeting advertisements and promoting content to users who have visited kinsta.com. — Nicolas Grekas. Make sure to bookmark this blog post for your future reference. This is where the OPcache extension comes in to play: “OPcache improves PHP performance by storing precompiled script bytecode in shared memory, thereby removing the need for PHP to load and parse scripts on each request.”. This one is pretty straightforward but bound to make a lot of people happy! See the following example from the RFC: With PHP 8, the code above would produce the following result (see the code in action here): If you unset the object, the key is automatically removed from the weak map: For a closer look at Weak maps, see the RFC. By submitting this form: You agree to the processing of the submitted personal data in accordance with Kinsta's Privacy Policy, including the transfer of data to the United States.

Even if this behavior is quite useful in several scenarios, it may produce wrong results that may also lead to bugs and/or security issues. This means that we are not forced to pass arguments to a function in the same order as the function signature: It’s also possible to combine named arguments with positional arguments: Another great advantage of named arguments is that they allow to specify only those arguments we want actually change and we don’t have to specify default arguments if we don’t want to overwrite default values. . Set by Hubspot. This collection of PHP tutorials will help you become a more well-rounded developer. Let's take a look at a few of the new additions in PHP 8 and who is supporting it at release. Stripe is our payment provider and they may set some cookies to help them with fraud prevention and other issues. Because PHP 8 has been on the horizon for so long, a lot of community work has already been done to make sure that it's supported across the web. Nevertheless, JIT could bring several benefits for developers. This RFC proposes to merge the constructor and the parameter definition. It’s the latest version of PHP so it is definitely more secure than PHP 7.4 and other older versions. Even if opcodes are in the form of low-level intermediate representation, they still have to be compiled into machine code. So, how did we get to JIT and what is the difference between JIT vs OPcache? Check out this excellent guide about how to enable JIT in PHP 8. Unify the various numeric string modes into a single concept: Numeric characters only with both leading and trailing whitespace allowed. Traits are defined as “a mechanism for code reuse in single inheritance languages such as PHP”. It went very smoothly. Furthermore, several frameworks provide helper functions to search for a value inside a given string (see Laravel Helpers documentation as an example). For example, arrow functions, null coalesce operator, ternary and elvis operators, etc. An explicit mixed type would allow people to add types to parameters, class properties, and function returns to indicate that the type information wasn't forgotten about, it just can't be specified more precisely, or the programmer explicitly decided not to do so. This situation would lead to a number of problems well explained in the RFC’s issues section. Web apps like WordPress also rely on other factors like TTFB, database optimization, HTTP requests, etc. The new version, PHP 8, promises to bring even more power and speed allowing for even better results. Full stack developer creating content at Auth0. Speed is everything. 2. Coming to PHP 8, the expectations of its users' have skyrocketed already.

PHP 8 Overview Currently, all properties have to be repeated several times (at least four times) before we can use them with objects. For an in-depht overview of object ergonomics in PHP, see this post and the following interview with Larry Garfield. Relative JIT contribution to PHP 8 performance (Image source: PHP 8.0 Announcement Addendum). Which one is your favorite? Two days ago the first “Alpha” of PHP 8 was presented, and PHP 8 is scheduled to release on November 26, 2020, only 5 months from now. An additional bonus of this is that it simplifies diffs where a parameter is added. Not doing so will result in a fatal error.”. OAuth2 and OpenID Connect: The Professional Guide. Interpreted languages, on the other hand, convert the source code as it's executed, which is much slower. Looking back, I see how previous major releases took PHP to the next levels. It may be enabled/disabled at PHP compile time and at run-time. PHP 8 brings several new functions to the language: Before PHP 8, strstr and strpos were the typical options for developers to search for a needle inside a given string. The potential to move more code from C to PHP, because PHP will now be sufficiently fast.”. Any other type of string is non-numeric and will throw TypeErrors when used in a numeric context. Simple 2. The Auth0 PHP SDK has been updated to fully support PHP 8 right out of the gate, so you can get up and running with it immediately! Apart from JIT, we can expect many features and improvements with PHP 8. WordPress. This cookie has not personal data it just indicates if you have signed up.

The following table compares the behavior of string to number comparison earlier PHP versions and in PHP 8: Read more about the many implications of this change and how string to number comparisons change in PHP 8 in the official RFC from Nikita Popov. “The benefits of the JIT compiler are roughly (and as already outlined in the RFC): So, while JIT will hardly bring huge improvements to WordPress performance, it’ll be upgrading PHP to the next level, making it a language many functions could now be written directly in. Community links will open in a new window. JIT brings compiled code to PHP, and with it, better performance — in some situations. So, how does OPcache make PHP faster? Real-Time Access Monitoring In long-running processes, this would prevent memory leaks and improve performance. ), this video where Nikita Popov of JetBrains interviews Nikolas Grekas. PHP 8 release is one of these major updates with a focus on performance thanks to its PHP 8 JIT compiler (Just in Time) added to new features which we will cover later in this article. You can accept all cookies at once or fine-tune your preferences in the cookie settings. This is the 6th.

Discover and enable the integrations you need to solve identity, support PHP 8 in their next release (v5.6), social identity providers (like Facebook, GitHub, Twitter, etc. Case Sensitive 6. Promoted properties are not allowed in abstract classes and interfaces: One of the most notable constraints is related to nullability. Here are some examples: So the constructor really belongs to a single class, and constructors between parent and child class do not have to be compatible in any way. WordPress Core aims to be compatible with PHP 8.0 in the 5.6 release (currently scheduled for December 8, 2020). The most acclaimed feature coming with PHP 8 is the Just-in-time (JIT) compiler. (Excluding + if both operands are array.). Marketing cookies help us target our ads better. • The throw statement will come in handy. What is JIT all about? We have made sure no personally identifiable information (PII) is sent by anonymizing IPs. Here is an example of an inheritance error with an interface: In PHP 7.4, the code above would throw the following error: A function in a child class with an incompatible signature would throw a warning. JIT “doesn’t introduce any additional IR (Intermediate Representation) form”, but uses DynASM (Dynamic Assembler for code generation engines) to generate native code directly from PHP byte-code. This means that the order in which arguments are passed won't matter, as the name will be used to determine the parameter. Now it’s your turn: are you ready to test the new PHP features? Generally, JIT compilers mostly benefit CPU-intensive applications, such as 3D rendering or large mathematical computations. The latest step in speeding up performance is the addition of the JIT compiler in PHP 8. Named arguments provide a new way of passing arguments to a function in PHP: Named arguments allow passing arguments to a function based on the parameter name, rather than the parameter position. I know. In your way PHP v10.0 will be very much alike Typescript. With PHP 8, the code we saw earlier above would prompt the following: In PHP, if an array starts with a negative index (start_index < 0), the following indices will start from 0 (more on this in array_fill documentation). Before version 8, PHP already supported two special union types: nullable and iterable. According to Dmitry Stogov: “JIT is extremely simple, but anyway it increases the level of the whole PHP complexity, risk of new kind of bugs and cost of development and maintenance.”. Union types accept values that can be of different types. You also agree to receive information from Kinsta related to our services, events, and promotions.

The most awaited of which is surely the Just in Time compiler, but there’s so much more with PHP 8. str_contains checks if $needle is found in $haystack and returns true or false accordingly. It extends \Exception and PHP throws this exception, every time you pass a value to a function, which has a valid type - but can not be used for the operation. WordPress plans to support PHP 8 in their next release (v5.6), which is currently scheduled for December 8th, 2020. This RFC intends to give string to number comparisons a more reasonable behavior: When comparing to a numeric string, use a number comparison (same as now). The proposal to include JIT in PHP 8 passed with 50 to 2 votes. The same happens when passing the same parameter name twice. Named arguments are particularly useful with class declarations because constructors usually have a large number of parameters and named arguments provide a more “ergonomic” way to declare a class. This corresponds to the normal three-year cycle for PHP. Attributes are added before the declarations they refer to. This proposal only relates to promoted parameters, i.e. Significantly better performance for numerical code.
