All of the POST variables will be stored in the HTTP_POST_VARS array which
you can loop through once rather than manually doing each seperate variable.

I have a bunch of variables (through a POST form) that I need to
loop through and check for content. Right now, each one is being
evaluated separately:
if ($var1 == '') {
$url .= "&var1=";
$error = 1;
} else {
$url .= "&var1=".urlencode(stripslashes($var1))."";
}
