[PHP] How to get the query string?

[Tamas Bucsu]

hi guys,

I'd like to get the query string the browser sends to the script. The problem is that 
since the $HTTP_POST_VARS (or $HTTP_GET_VARS ) is an associative array I can't use 
numbers to point to the elements of this array. This piece of code does not work:

for ($a=1;$a<=sizeof($HTTP_POST_VARS);$a++){
 echo "$a. ".$HTTP_POST_VARS[$a]."<br>";
}

Please help
