Read on to find out more about the new features in the latest version of PHP.
New features
Let’s dive into some of the new features that PHP 8.3 Beta3 brings to the table. This release may not be notable for radical changes or major updates, but it does introduce some key features that could significantly improve the PHP development experience.
gc_status() returns additional GC information
Long-running daemons and cron jobs have always been a weak point in PHP in general. However, with PHP 8.3, the gc_status() function now returns additional garbage collection (GC) information. This is a significant improvement for developers who need to manage memory usage in long-running scripts. You can find more information about this feature here .
class_alias() supports Aliasing Built-in PHP Classes
Another interesting feature of PHP 8.3 is the ability to add aliases to PHP classes using the class_alias() function . This allows PHP developers to hook into predefined classes and override classes or declarations in them. This feature opens up a world of possibilities for extending and customizing the behavior of PHP classes.
json_validate() function
Another interesting addition in PHP 8.3 is the json_validate() function. This function validates whether a string contains valid JSON, providing a more efficient alternative to userland implementations that use json_decode(). The json_decode() function generates a ZVAL (object/array/etc.) while parsing the string, using otherwise saved memory and processing. The json_validate() function uses the same JSON parser that exists in the PHP core and is used by json_decode(), ensuring that what is valid in json_validate() is also valid in json_decode().
How to Test PHP 8.3 (Beta3) on SiteGround Servers
