why is $_REQUEST empty
提问by Hawkseye
I have Ubuntu 10.10 with apache2, php 5.3.3-1 and mysql 5.1.
我有带有 apache2、php 5.3.3-1 和 mysql 5.1 的 Ubuntu 10.10。
I am passing some values to a page via URL. On that page, if I do print_r($_GET), then I see the array contents. But if I do print_r($_REQUEST)the array is empty. Any ideas why this could be?
我通过 URL 将一些值传递给页面。在那个页面上，如果我这样做了print_r($_GET)，那么我会看到数组内容。但是如果我这样做print_r($_REQUEST)数组是空的。任何想法为什么会这样？

Also try check "request_order"option in php.ini:
还可以尝试检查php.ini 中的“request_order”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"

if your post body larger than post_max_size or upload_max_filesize which in the php.ini may be cause $_POST and $_REQUEST empty too.
如果您的帖子正文大于 php.ini 中的 post_max_size 或 upload_max_filesize 也可能导致 $_POST 和 $_REQUEST 为空。
