比如list.php?USERID=1
我取值的时候必须是$_GET["USERID"],用$_GET["userid"]就取不到值。什么地方可以设置吗？


回复讨论(解决方案)

那你url的参数就直接小写好了。。。  怕用户误输入  大小不一 那就强行全转成小写的

没有地方设置，因为 php 的变量（关联键）是区分大小写的
比如 $A 和 $a 就是两个变量

不过你可以用 array_change_key_case 函数将数组的关联键改成全为小写或大写的 

$input_array = array("FirSt" => 1, "SecOnd" => 4);print_r(array_change_key_case($input_array, CASE_LOWER));
Copy after login
Array(    [first] => 1    [second] => 4)
Copy after login
