What are some best practices for reversing strings with Umlauts in PHP?

When reversing strings with Umlauts in PHP, it is important to handle multibyte characters properly to ensure that the Umlauts are not corrupted or lost during the reversal process. One way to achieve this is by using the mb_strlen() and mb_substr() functions to work with multibyte characters. 

function reverseStringWithUmlauts($string) {
    $length = mb_strlen($string);
    $reversedString = '';
    
    for ($i = $length - 1; $i >= 0; $i--) {
        $reversedString .= mb_substr($string, $i, 1);
    }
    
    return $reversedString;
}

// Example usage
$string = 'über';
$reversedString = reverseStringWithUmlauts($string);
echo $reversedString; // Output: rebeü
