Strpos With an Array of Needles

Here’s a quick function to search a string for the position of several string occurrences. Once one is found, it returns the position.

// strpos with an array of $needles
function strposa($haystack, $needles) {
	if (is_array($needles)) {
		foreach ($needles as $str) {
			if (is_array($str)) {
				$pos = strposa($haystack, $str);
			} else {
				$pos = strpos($haystack, $str);
			}
			if ($pos !== FALSE) {
				return $pos;
			}
		}
		return FALSE;
	} else {
		return strpos($haystack, $needles);
	}
}
