you can use isset()
better grab a PHP starter document or tutorial.

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
