Question

Which is better to use when I use _GET[‘something here’] for a variable to check if it is empty or not

if (isset($_GET['url']) != '') {
    //do stuff with it
}

OR

if (isset($_GET['url']) != NULL) {
    //do stuff with it
}

” or null or something else?

Please don’t call this over optimizing or micro optimizing, I am simply looking for best practices, thank you

You should do the following to be sure that the value both exists and isn’t empty

if(isset($_POST[myField]) && $_POST[myField] != "") {
Do my PHP code
}
