What I mean:
Example
$pattern = '/^[s]{1,5}/';
$str = 'sssssssssssss';
$a = preg_match($pattern, $str);
echo $a; // $a => 1 (true)
But I need to validate only strings below 6 symbols length. Allowed to use only regular expressions!

5You could add an anchor `$` to the end of the pattern `^s{1,5}$` – The fourth bird Apr 17 '20 at 06:29

1`$a = strlen($str) < 6;`? – Nick Apr 17 '20 at 06:33

1@Thefourthbird: `\z` is a better choice than `$`, otherwise `^s{1,5}$` will also match the string `"sssss\n"`. – Casimir et Hippolyte Apr 17 '20 at 23:42
