其实这是在PHP的配置文件里面设置的,让我们来看一下php.ini这个配置文件,在第466行左右有如下内容:
 This directive describes the order in which PHP registers GET, POST, Cookie ;
 Environment and Built-in variables
 (G, P, C, E & S respectively, often ; referred to as EGPCS or GPC).
Registration is done from left to right, newer ;
values override older values. variables_order = "EGPCS"
这个EGPCS就是说明用$_REQUEST数组获取内容的优先级,
其字母的含义分别代表为:E代表$_ENV,G代表$_GET,P代表$_POST,
C代表$_COOKIE,S代表$_SESSION。
