When I'm validating form data, there are many occasions (more than
not) that I require most of them to be completed, and not left blank.
In which case you would do:
if(empty($_GET['var1'], $_GET['var2'], $_GET['var3'])){
//Display error, yadda yadda
}
as aposed to
if(empty($_GET['var1']) || empty($_GET['var2']) || empty($_GET['var3'])){
//Display error, yadda yadda
}
which is a much cleaner and simpler method. Doing it the other way (AND/OR)
doesn't seem to have many applications that I can see.
