The principle of the PHP cache Accelerator for lamp and LNMP environments

LAMP Environment PHP how the Cache accelerator works  

lamp=linux+apache+mysql+php

1. Apache receives the client's PHP program request and filters it according to the rules.

2.Apache sends PHP program request to PHP processing module libphp5.so.

The 3.PHP engine locates the PHP file on the disk and loads it into memory for parsing.

The 4.PHP processing module libphp5.so the PHP source code into an opcode.

The 5.PHP processing module libphp5.so executes the opcode and caches the opcode.

6. Apache receives a new PHP program request from the client, and the PHP engine directly reads the cache execution opcode file.

Lnmp Environment PHP how the Cache accelerator works

lamp=linux+nginx+mysql+php

1. Nginx receives the client's PHP program Access request.

2. Nginx passes the PHP program request to the FCGI (PHP-FPM) process that parses PHP based on filtering rules such as extension.

3. the PHP fpm process calls the PHP parser to read the PHP file on the site disk and load it into memory.

The 4.PHP parser compiles the PHP program into an opcode file and caches the opcode.

After the 5.PHP fpm engine executes the opcode, it returns the data to Ngnix and returns the client.

6.Nginx receives a client's new PHP program request, the PHP fpm engine reads the opcode in the cache and executes it, returning the result.
