Question

If I were to call:

www.*.com?hello

if($_GET["hello"]){
}

It will always return false because ?hello variable needs to be set as something…

Is there a way to get the ? part without setting the variable to anythign before hand?

Answer 1

You can check if variable is set like this:

if(isset($_GET["hello"])){

}

sometimes key_exists() is better because if $_GET["hello"] == null you can get false

if (key_exists("hello", $_GET)) {

}
