What are some best practices for handling string manipulation in PHP to ensure efficient and effective output truncation?

When handling string manipulation in PHP, it is important to ensure efficient and effective output truncation to avoid performance issues and improve user experience. One best practice is to use built-in PHP functions like substr() to truncate strings to a specific length. Additionally, consider using mb_substr() for multibyte character support to avoid cutting off characters in the middle of a multibyte character. 

// Truncate a string to a specific length using substr()
function truncateString($string, $length) {
    if (strlen($string) > $length) {
        return substr($string, 0, $length) . '...';
    } else {
        return $string;
    }
}

// Example usage
$string = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$truncatedString = truncateString($string, 20);
echo $truncatedString; // Output: Lorem ipsum dolor si...
