PHP Caching principle

When the client requests a PHP program, the server's PHP engine parses the PHP program and compiles it into a specific opcode (operatecode, abbreviated opcode) file, which is a binary representation of the PHP code. By default, this compiled opcode file is discarded by the PHP engine, and the opcode cache (Opcode cache) is the principle of saving the compiled opcode to shared memory so that the next time the same PHP program is called again, the code is reused, avoiding repeated compilation of the same It saves the PHP engine time to compile repeatedly, reduces server load and saves CPU and memory overhead, and the main cache accelerator plug-ins are eaccelerator, XCache, Zendopcache and so on.

XCache Cache plug-in deployment

XCache is an open source, fast and stable Phpopcode Cache plugin whose project leader was once a member of LIGHTTPD's development. XCache the php compiled opcode to the shared memory, avoid the same program repeatedly compiled. When users request the same PHP program, they can directly use the data that has been compiled in the cache to improve access to PHP, typically up to 2-5 times faster, and significantly reduce server load overhead. Many companies use XCache, which has been able to run stably in a high-volume, heavy-duty production environment, better than the same type of Opcache cache plug-in, while XCache community is active, fast-developing and able to quickly follow up on PHP version updates. The current 3.2 version fully supports php5.1-5.6, the official website http://xcache.lighttpd.net

Zendopcache Cache plug-in deployment starting from PHP5.5, the official has integrated a new generation of cache accelerator plug-in Zendopcache, compile PHP with only a--enable-opcache, according to the official said cache faster. For earlier versions of PHP, you need to install Zendopcache in the form of an extension that supports php5.3-5.4.

What is Phpize?

With Phpize you can build a PHP plug-in module, before compiling the extension module to be added, you need to perform a phpize.
