My testing shows that it works its way down the switch cases until the first match just like the match is doing here. So perhaps it's just me but I don't believe this is true. In some cases, this might result in a significant performance increase! ![]() This is the only way to guarantee that your site will run properly. Important steps include: Static analysis Unit testing Integration testing Manual testing When switching to PHP 8.x, ensure everything has been properly tested. ![]() It utilizes a strict type of comparison and doesn't do any sort of coercion. The match can return values, doesn't need lengthy statements like a switch. The match expression will start by resolving the first arm's condition, stop if it evaluates to true, and so on. To switch to PHP 8.0 or higher for your website, there are several steps that you, or your developer, must perform. The match expression presented in PHP 8 is like the switch statement. Download PhpStorm 2021.3 Here are the highlights of the release: Full support for PHP 8. You can read all about the nullsafe operator here.A switch statement would execute all these regex functions before evaluating each arm. PhpStorm 2021.3 is now available This major release introduces full support for PHP 8.1, better handling of generics in PHP, remote development, improvements to deployment, an HTTP client, refactorings, and much more. With the addition of the nullsafe operator, we can now have null coalescing-like behaviour on methods! $dateAsString = $booking-> getStartDate()?-> asDateTimeString() $dateAsString = $startDate ? $startDate-> asDateTimeString() : null Instead you need intermediate checks, or rely on optional helpers provided by some frameworks: $startDate = $booking-> getStartDate() If you're familiar with the null coalescing operator you're already familiar with its shortcomings: it doesn't work on method calls. Fixed bug GH-11189 (Exceeding memory limit in zendhashdoresize leaves the array in an invalid state). Fixed bug GH-9068 (Conditional jump or move depends on uninitialised value(s)). Core: Fixed bug GH-11152 (Unable to alias namespaces containing reserved class names). If you want to know more about what the JIT can do for PHP, you can read another post I wrote about it here. PHP 8 ChangeLog 8.2 8.1 8.0 Version 8.2.7. I've done my own benchmarks on real-life web applications, and it seems like the JIT doesn't make that much of a difference, if any, on those kinds of PHP projects. The previous wave of courses for Mario Kart 8 Deluxe dropped in March, bringing a brand-new course, Yoshi’s Island, and a returning racer, Birdo, to the Switch game. The JIT - just in time - compiler promises significant performance improvements, albeit not always within the context of web requests. Public function bar ( ?Bar $bar): void # JIT RFC Furthermore, nullable unions can be written using |null, or by using the existing ? notation: public function foo ( Foo|null $foo): void Note that void can never be part of a union type, since it indicates "no return value at all". ![]() public function foo ( Foo|Bar $input): int| float PS: both versions of PHP have be installed for these commands to work. For example, to switch between PHP 7.4 and PHP 7.3. Union types are a collection of two or more types which indicate that either one of those can be used. If you have both versions of PHP installed, you can switch between versions using the link and unlink brew commands. In this article, we’ll look at eight of the biggest enhancements offered by PHP 8. It’s a major new version that upgrades the language with additional features and performance improvements. Given the dynamically typed nature of PHP, there are lots of cases where union types can be useful. James Walker Jan 6, 2021, 8:00 am EDT 4 min read PHP 8 was released at the end of November 2020. Let's start with all new features, it's quite a list!
