If you have for example a variable in your URL say url.php?var= and some one types in %00 the
variable will pass isset. For post and get variables I wrote this function to filter out varables
that are set but empty.
function isval($inp){
if(isset($inp)){
$len = strlen($inp);
if($len > 0){
return true;
}
else{
return false;
}
}
else{
return false;
}
}
