변수 우선순위에 의해서 Get이 우선권을 가질 듯?

$ vi /etc/php5/apache2/php.ini ; This directive determines which super global data (G,P & C) 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"
