Hi everybody, I'm trying to migrate our PHP code base to PHP5. For the most part the transition hs been smooth however I'm really stuck on a regular expression which gives different results in 4.4 and 5.2. I've looked through migration guides but as far as I can see nothing should have changed in Regex handling between the versions. I've created the following script below to test the match: <?php include( 'input.inc' ); $pattern = "/<!T_([^> ]+)([^>]*)>(.*?)<!T_end\\1>|<!T_([^> ]+)([^>]*)>/si"; preg_match_all( $pattern, $string, $matches ); echo phpversion(); var_dump($matches); ?> Input.inc contains the string that is giving the different results - its probably to long to include so you can find it at http://www.workingweb.nl/example/input.inc. The results of this being run can be seen at: PHP4 (desired result) - http://www.workingweb.nl/example/php4results PHP5 - http://www.workingweb.nl/example/php5results If the pattern modifier 's' is removed the regex behaves consistently again (but this breaks other pages on our website so can't be used as a workaround). Besides I don't see why that should make any difference. Here is the version information from the PHP CLI versions I've been testing with: user@debian:~$ php4 -v PHP 4.4.4-8+etch6 (cli) (built: May 16 2008 15:59:34) Copyright (c) 1997-2006 The PHP Group Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies user@debian:~$ php5 -v PHP 5.2.0-8+etch11 (cli) (built: May 10 2008 10:46:24) Copyright (c) 1997-2006 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2006 Zend Technologies Any help on this would be very appreciated. Thanks, Ewen
