How do I use OPcache in PHP?

OPcache can only be compiled as a shared extension. If you have disabled the building of default extensions with –disable-all, you must compile PHP with the –enable-opcache option for OPcache to be available. Once compiled, you can use the zend_extension configuration directive to load the OPcache extension into PHP.

What is Php_opcache?

OPcache is a caching engine built into PHP. When enabled, it dramatically increases the performance of websites that utilize PHP. From php.net: 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.

What is the use of OPcache?

OPcache is a type of caching system that saves precompiled script bytecode in a server’s memory called a cache, so each time a user visits a web page, it loads faster.

Is PHP a JIT?

The JIT Compilation approach in PHP 8 means significantly better performance for numerical calculations and slightly better performance for typical PHP web applications. JIT compilation also unlocks the potential to move code from C to PHP, because PHP is now sufficiently fast.

Does PHP Cache code?

PHP ‘output caching’ saves a chunk of data somewhere that can later be read by another script faster than it can generate it. ‘Parser caching’ is specific feature. PHP is a scripting language and code is not compiled or optimized to a particular computer. Every PHP file must be parsed and that takes time.
