为什么 $_REQUEST 是空的

php arrays request

2022-08-30 23:36:49

我有Ubuntu 10.10和apache2，php 5.3.3-1和mysql 5.1。

我正在通过URL将一些值传递给页面。在该页面上，如果我这样做，那么我会看到数组内容。但是如果我这样做，数组是空的。任何想法为什么会这样？print_r($_GET)print_r($_REQUEST)

也请尝试检查php中的“request_order”选项.ini：

; 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"

如果你的帖子正文大于post_max_size或upload_max_filesize在php中.ini可能会导致$_POST和$_REQUEST空。
