PHP is a general-purpose scripting language geared towards web development. PHP code is usually processed on a web server by a PHP interpreter implemented as a module, a daemon or as a Common Gateway Interface (CGI) executable.

By default Nginx is not capable of processing dynamic web pages with PHP so it requires the use of specific additional plugins for this purpose. One of these plugins is FPM (FastCGI Process Manager). FPM is an alternative PHP FastCGI implementation with some additional features (mostly) useful for heavy-loaded sites. It is the preferred method of processing PHP pages with Nginx and is faster than traditional CGI based methods.

PHP 8.2 has been released on December 8, 2022. We'll go through most important features, performance improvements, changes and deprecations one by one.

Read only properties were introduced in PHP 8.1. Now, PHP 8.2 is adding support to declare the entire class as read only.

If you declare a class as read only, all its properties will automatically inherit the read only feature. Thus, declaring a class read only is the same as declaring every class property as read only.
