檢查php.ini文件request_order。可能它沒有正確設置。

http://php.net/manual/en/ini.core.php#ini.request-order

; 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"
