call a function from include file.

[Anon]

I am trying to call a function from include
file but it does not work and no errors shown.

include file: engine.php

<?php
function idout(){
print $QUERY_STRING;
}
?>

parent php file: test3.php

<?php
include("engine.php");
idout();

?>

and this request does not print anything
not even errors.
localhost/test3.php?abc

The variable QUERYS_STRING is a local variable to the function. Either declare QUERY_STRING a global variable or pass the value to the function.
