A function reads a mysql record into an array and returns it, if it
doesnt exist it returns '' or FALSE.

What ways do I have to test that my returned array is not empty

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

If you want an empty string, false, and an empty array handled seperately, you can use the following:

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