How to check if $_GET is empty?

How to check if $_GET is empty?

You said it yourself, check that it's empty:

if (empty($_GET)) {
    // no data passed by get
}

See, PHP is so straightforward. You may simply write, what you think ;)

This method is quite secure. !$_GET could give you an undefined variable E_NOTICE if $_GET was unset (not probable, but possible).

i guess the simplest way which doesn't require any operators is

if($_GET){
//do something if $_GET is set 
} 
if(!$_GET){
//do something if $_GET is NOT set 
}
