ok going mad all I need to do is check a variable and if it has a number in
it then do something, so anything from 0 up, but it keeps thinking 0 is null
and failing, anyway around this? or am I just being stupid as usual?
$_SESSION["temp"] = 0;
$tempVar = 0;
if($_SESSION["temp"] !=""){ echo "!= condition<br>"; }
if(isset($_SESSION["temp"])){ echo "isset condition<br>";}
if(isset($tempVar)){ echo "tempVar isset condition<br>";}
if($tempVar !=""){ echo "tempVar != condition<br>";}
if(!empty($tempVar)){ echo "tempVar !empty condition<br>";}
