how to find the error:

  1. Enable error output
  2. go to https://translate.google.com/ and insert the text of the error, look at the translation.
  3. Aha $ j not defined
  4. do var_dump before if var_dump($v == $search,$v,$search)
  5. aha does not work why?
  6. Yes, because a pancake in $v has spaces, newlines, and so on.
  7. Trim before comparison if(trim($v) == trim($search))
  8. everything is working!
