Create slug.php file

<code data-enlighter-language="php" class="EnlighterJSRAW">function display_name_slug($string, $wordLimit = 30){
    $separator = '-';
    
    if($wordLimit != 0){
        $wordArr = explode(' ', $string);
        $string = implode(' ', array_slice($wordArr, 0, $wordLimit));
    }

    $quoteSeparator = preg_quote($separator, '#');

    $trans = array(
        '&.+?;'                 	=> '',
        '[^\w\d _-]' 				=> '',
        '\s+'                   	=> $separator,
        '('.$quoteSeparator.')+'	=> $separator
    );

    $string = strip_tags($string);
    foreach ($trans as $key => $val){
        $string = preg_replace('#'.$key.'#i'.('UTF8_ENABLED' ? 'u' : ''), $val, $string);
    }

    $string = strtolower($string);

    return trim(trim($string, $separator));
}

You can call this function display_name_slug($string=’pass any string here’, $wordLimit = 30) you can choose any limit of string to return, for now I mention 30
