Description:
------------
I'm using quantifiers in preg_match_all functions,amongst other things,
to restrict the length of strings strings submitted from HTML forms. The
lower limit catches discrepant strings, but the upper limit has no
effect. I've tried using very basic code, but unsuccessfully.
Reproduce code:
---------------
$failure = 0;
$userpattern = "/t{3,6}/";
$username = 'ttttttt';
$usercheck = preg_match_all($userpattern,$username,$results);
if ( !$usercheck )
{ $failure++; }
Expected result:
----------------
$usercheck = 'tt';
This would be a disallowed string
$usercheck = 'ttttttt';
This would also be a disallowed string
Actual result:
--------------
$usercheck = 'tt'; results in $failure == 1 & the string 'fails' as it
should.
$usercheck = 'ttttttt'; results in $failure = 0 & the string is
allowed.
This happens however many repetitions the string comprises and with any
upper limit set.
