hi:

i have this code wich always is returning true for
isset($_SERVER['QUERY_STRING']) even when calling the page without
passing vars through the url

$thisURL = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$qs = 1;
$thisURL .= "?".$_SERVER['QUERY_STRING'];
}

for example, typing in the browser:
http://mac.local/~admin/.../home.php

echoes:
PHP_SELF: /~admin/.../home.php
QUERY_STRING:
$thisURL: /~admin/.../home.php?

do i need to unset $_SERVER['QUERY_STRING']???

OSX 10.4, PHP 5.0.4

tia,

jdoe

isset() tells you whether the variable has been defined - nothing more,
nothing less.

The correct way to test without generating any errors or notices is this:

if (isset($_SERVER['QUERY_STRING']) && !empty($_SERVER['QUERY_STRING'])) {

I don't like using isset(), had various problems with it on different
systems.

Try changing isset() to strlen() ie

if(strlen($_SERVER['QUERY_STRING']) > 0){

}

And see if that works, will only be true if there are actually some
characters contained in $_SERVER['QUERY_STRING']
