php - 为什么 $_REQUEST 是空的

Question

我有带有 apache2、php 5.3.3-1 和 mysql 5.1 的 Ubuntu 10.10。

我正在通过 URL 将一些值传递给页面。在那个页面上，如果我执行 print_r($_GET)，那么我会看到数组内容。但是，如果我执行 print_r($_REQUEST)，则数组为空。知道为什么会这样吗？

也尝试检查 "request_order" php.ini 中的选项:

; This directive determines which super global data (G,P,C,E & S) should
; be registered into the super global array REQUEST. If so, it also determines
; the order in which that data is registered. The values for this directive are
; specified in the same manner as the variables_order directive, EXCEPT one.
; Leaving this value empty will cause PHP to use the value set in the
; variables_order directive. It does not mean it will leave the super globals
; array REQUEST empty.
; Default Value: None
; Development Value: "GP"
; Production Value: "GP"
; http://php.net/request-order
request_order = "GP"
