function dump($vars, $label = , $return = false){
If (ini_get(html_errors)) {
$content = "
} else {
$content = $label . " : " . print_r($vars, true);
}
If ($return) { return $content; }
echo $content;
Return null;
}
If (ini_get(html_errors)) {
$content = "
";<br>
If ($label != ) {<br>
$content .= "<strong>{$label} :</strong>
";<br>
}<br>

array_remove_empty($arr[$key]);
} else {
$value = trim($value);
if ($value == ) {
unset($arr[$key]);
} elseif ($trim) {
$arr[$key] = $value;
}
}
}
}
foreach ($arr as $key => $value) {
If (is_array($value)) {
array_remove_empty($arr[$key]);
