Posted 2021-02-26

/**
 * jquery style extend, merges arrays (without errors if the passed values are not arrays)
 *
 * @return array $extended
 **/
function extend() {
	$args = func_get_args();
	$extended = array();
	if(is_array($args) && count($args)) {
		foreach($args as $array) {
			if(is_array($array)) {
				$extended = array_merge($extended, $array);
			}
		}
	}
	return $extended;
}
