HTML Form inside PHP

Hello.

I’ve got a slugify word function :

  static public function slugify($text)
  { 
    $text = str_replace(" ", "_", $text);
    

    $text = str_replace(",", "", $text);
    $text = str_replace(".", "", $text);


    // replace non letter or digits by -
    $text = preg_replace('~[^\\\\pL\\d_]+~u', '-', $text);

    // trim
    $text = trim($text, '-');

    // transliterate
    $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);

    // lowercase
    $text = strtolower($text);

    // remove unwanted characters
    $text = preg_replace('~[^-\\w]+~', '', $text);

    if (empty($text))
    {
      return 'n-a';
    }

    return $text;

  }

my question is , if possible is to slugify a word typed in html input (text) and then update a form with a converted word? of course all the action after pressing buttong “submit”.

e.g.

We’ve got a word : Ri ch, a.r.d,

After a function its converted to a Richard

Converting is pretty easy , but it’s possible to update a html input with php?
I know that JQuery provide this issue , but I would like to do it in PHP.

I fixed it , btw if anyone is interested :

After slugify a word pass it to a variable then as a html form value.
