php5 通用兼容的公共文件.

每次新项目, 都要为环境配置做许多php的修正, 为此, 我整理了这一份通用的php抬头文件. 
使用方法, 将代码保存为某个php文件, 然后在项目中引入即可. 

代码作用如下: 
  1: 规范化编码问题, utf-8, 时间区域, 数字长度都有变更. 
  2: 规范化字符转义问题, 全部采用php5.3之后的标准, 都不转化. 
  3: session, gzip做判断启动. 这有利于防止隐性冲突. 
  4: 对server数组进行整理, 隐藏掉一些非安全段, 增加以http_开头的一些数据, 如内存占用, 起始时间, 当前url地址, ip, get, post等等. 你只要打印出$_server数组, 基本上许多数据就都有了, 并且它是超全局的.
