Something like the following?
<?php
if(empty($array)) echo '$array is empty';
?>

If you want an empty string, false, and an empty array handled seperatel=
y, =

you can use the following:

<?php
if($return=3D=3D=3Dfalse){ //notice the triple '=3D'
echo 'Function returned false';
} else if($return =3D=3D=3D ''){
echo 'Function returned empty string.';
} else if(is_array($return) && empty($return)){
echo 'Function returned empty array.';
} else {
echo 'Function returned:';
var_dump($return);
}
?>
