PHP使用str_slug而不更改Upper Cases

Question

Want to change text into slug using str_slug. It works perfectly for different cases, but I want it to work without changing UpperCases, i.e.

ex: Hello --- World => Hello-World

Is there a way to get what I want?

As stated on a question on laracasts.com you can create your own version of the helper function, that leaves out mb_strtolower():

public static function slug($title, $separator = '-', $language = 'en')
{
    $title = static::ascii($title, $language);
    // Convert all dashes/underscores into separator
    $flip = $separator == '-' ? '_' : '-';
    $title = preg_replace('!['.preg_quote($flip).']+!u', $separator, $title);
    // Replace @ with the word 'at'
    $title = str_replace('@', $separator.'at'.$separator, $title);
    // Remove all characters that are not the separator, letters, numbers, or whitespace.

    // With lower case: $title = preg_replace('![^'.preg_quote($separator).'\pL\pN\s]+!u', '', mb_strtolower($title));
    $title = preg_replace('![^'.preg_quote($separator).'\pL\pN\s]+!u', '', $title);

    // Replace all separator characters and whitespace by a single separator
    $title = preg_replace('!['.preg_quote($separator).'\s]+!u', $separator, $title);
    return trim($title, $separator);
}
