Replacing bad words in a message with asterisks

Question

PHP

I am replacing bad words in messages with PHP.
I did not find a ready-made solution, I do something like this:

    public static function replaceFuckWords($message)
    {
        $pattern = '/ahole|ash0le|f u c k|bi.+ch/i'; // здесь сейчас не все слова, список будет большой
        return preg_replace($pattern, '*****', $message);
    }

That is, the regular expression finds such words and changes them to five asterisks. All OK.

But you need to replace it not with five stars (as it is now), but with the number corresponding to the found bad word.
For example, cipa should be replaced with **** (four asterisks), and fatass should be replaced with ****** (six asterisks) Does

anyone have a ready-made solution, or an idea how to implement it? I will be grateful, thanks.

Answer 1

You can modify your code like this:

function replaceFuckWords($message)
{
    $pattern = '/(ahole|ash0le|f u c k|bi.+ch)/ie';
    return preg_replace($pattern, "str_repeat('*', strlen('$1'))", $message);
}

The essence of the e modifier (PREG_REPLACE_EVAL).

Be careful with patterns! I remember once I flew out of the chat while trying to enter the word "turpentine". It is unlikely that your users will be delighted with such a turn of events.
