How can PHP accurately count the length of strings containing Umlauts in preg_match?

When using preg_match to count the length of strings containing Umlauts (such as ä, ö, ü), PHP may not accurately count the length due to the multi-byte nature of these characters. To accurately count the length of strings with Umlauts, you can use the mb_strlen function in PHP, which supports multi-byte characters. 

$string = "Möglichkeiten"; // Example string containing Umlauts
$length = mb_strlen($string, 'UTF-8'); // Count the length of the string using mb_strlen with UTF-8 encoding
echo $length; // Output the accurate length of the string
