Just as an addition - this special case could also be handled without a
reference, for example:

<?php
function MyFunc ($input)
{
if (!empty($input))
return array($input, date('H:m:s'));
else
return false;
}

if ($a = MyFunc('Hello'))
print_r($a);
else
echo 'Empty input!';
?>

Or, if you need to change an existing array:

<?php
function MyFunc ($input, $arr)
{
if (!empty($input)) {
$arr[] = $input;
$arr[] = date('H:m:s');
return $arr;
}
else
return false;
}

$arr = array('some', 'data');
if ($new_arr = MyFunc('Hello', $arr))
$arr = $new_arr;
else
echo 'Empty input!';
print_r($arr);
?>
