i 开发者_如何学运维have coded a site in Procedural style in PHP, now to improve performance i need to compile them. I dont hav a good idea on PHP code compilation ! so need some help on how to do it for Procedural style code !

PHP is not a traditionally compiled language. There's the Facebook HipHop PHP C++ compiler/transformer, but you should have very specific reasons before you start using it. The usual way to speed up PHP scripts beyond what can be done by internal optimization is by using opcode caching on the executing server.
