PHP 4.0 Bug #7222 Updated: ereg_replace, ereg

ID: 7222 Updated by: torben Reported By: zibin@tx.technion.ac.il Status: Closed Bug Type: *Regular Expressions Assigned To: Comments: I don't believe that this is a bug--those aren't valid POSIX regular expressions. It looks like you're trying to use a perl-style non-greedy operator (?) after the .* piece, which isn't part of the POSIX regex syntax. For more information on POSIX regex syntax, check out the manual page which comes with the PHP source--in PHP 4, it's located in /path/to/php4/regex/regex.7. You can read it by doing something like: % man /path/to/php4/regex/regex.7 If you want to use non-greedy type regexes, you should use the perl- compatible functions; if you want to catch all of the instances found in a string, use preg_match_all(). Something like this: if (preg_match_all('/onlyuser\[(.*?)\]/i', $inside, $regs)) { var_dump($regs); } Check out http://www.php.net/manual/function.preg-match-all.php and the manual entries on syntax and pattern modifiers for more information.
