Bad Word Filter, how do I replace words by their length?

Question

I have this PHP Code, it generates random characters where there is a bad word:

$wordreplace = array (
  \"!\",
  \"#\",
  \"@\",
  \"&\",
  \"^\",
  \"$\",
         


        

Answer 1

for replace bad words in string you can use preg_replace_callbackto perform a regular expression search and replace using a callback.

below example replace all bad words with *

output :

PHP is a ***ular general-purpose scripting language that is especially suited to web *****opment.

 $value) {

        $start = strpos($ocr[0],$value);
        if($start!== false){
            $length = strlen($value);
            $newstr = substr_replace($ocr[0],str_repeat("*",$length),$start,$length);
        }

        }

    return $newstr ? $newstr :  $ocr[0];

}
