function dump ($vars, $label = ", $return = False) {
if (Ini_get (' html_errors ')) {
$content = "
$content. = "{$label}:
$content. = "\ n
\ n ";
} else {
$content = $label. ": \ n". Print_r ($vars, true);
}
if ($return) {return $content;}
Echo $content;
return null;
}
Array_remove_empty () removes empty elements from the array
Function Array_remove_empty (& $arr, $trim = True) {
foreach ($arr as $key = = $value) {
if (Is_array ($value)) {
Array_remove_empty ($arr [$key]);
} else {
$value = Trim ($value);
if ($value = = ") {
Unset ($arr [$key]);
} elseif ($trim) {
$arr [$key] = $value;
