It would seem that array_merge doesn't do anything when one array is empty (unset):
<?php //$a is unset
$b = array("1" => "x");
$a = array_merge($a, $b});
//$a is still unset.
?>
to fix this omit $a if it is unset:-
<?php
if(!IsSet($a)) {
$a = array_merge($b);
} else {
$a = array_merge($a, $b);
}
?>
I don't know if there's a better way.
