Create Zend OpCache guidance document

[WesRapyd]

OPcache is a PHP extension that significantly improves WordPress performance by storing precompiled PHP code in the server's memory, essentially reducing the need to recompile the same code every time a page is loaded, resulting in faster website loading times for users; making it an essential component for optimizing WordPress sites.

Key points about OPcache:

Function:
It compiles human-readable PHP code into a format that the server can understand quickly (called opcode), and then stores this compiled code in the cache for immediate access.

Benefits for WordPress:
Faster page load times: By eliminating the need to repeatedly compile PHP code, OPcache significantly reduces processing time on the server.
Improved performance under high traffic: When many users visit a site simultaneously, OPcache helps maintain fast loading speeds by readily accessing cached code.

How it works:
When a PHP script is executed, OPcache checks if the compiled version is already in the cache.
If the compiled code exists, it is immediately used to execute the script.
If not, the script is compiled into opcode and stored in the cache for future use.
