So if I have a url main.php?res=2 with this code in it

Code:
<?
//$res = 3;
echo "res =".$res;
?>

Why can't I see the variable? (I want to see "res = 2")

(If I uncomment out the second line in the code above I do get the result "res = 3")

:/

Do you mean something like this?


[php]
<?
// thisFile.php?someVar=123

$someVar= $_GET['someVar'];
if (!$someVar) {
die("<p>You didn't specify someVar</p>");
}

$stringOut = "You passed ($someVar) as a value via the URL";
echo ($stringOut);
?>
[/php]

Yep, had just found it, many thanks though.

Code:
echo "res = ".$_GET['res'];

Has to do with global variables being off it appears, but I can't remember encountering the need for that syntax before.
