Hello,
Could you tell me why on PHP 4.2.2 this code work
<?php
switch ($_GET['fuseaction'])
{
case 0:
print "i equals 0";
break;
default:
print "i is not equal to 0, 1 or 2";
}
?>
and this one not :
<?php
switch ($fuseaction)
{
case 0:
print "i equals 0";
break;
default:
print "i is not equal to 0, 1 or 2";
}
?>
In both cases when fuseaction is not defined, I receive an error. Could you
tell me how to know if the variable is defined in the URL. In coldfusion you
can do <cfif isDefined("URL.fuseaction")>
but in php ?
Bye
