<?php$_GET['foo'] = 'a';$_POST['bar'] = 'b';var_dump($_GET);var_dump($_POST);echo "<br>";var_dump($_REQUEST); // 内容没有包含 'foo' or 'bar'?>

$_REQUEST ? HTTP Request 变量 说明 默认情况下包含了 $_GET,$_POST 和 $_COOKIE 的数组。
var_dump($_REQUEST); // 内容没有包含 'foo' or 'bar'?


回复讨论(解决方案)

$_REQUEST、$_GET、$_POST 保存的都是传入的数据
在代码中赋值的不算

 这个测试告诉我们request是php初始化的独立变量,并非实时从get或post变量读取
