Description: ------------ I needed to add a dash to a character class, so I appended it to the present character class definition. It turns out that it wouldn't accept unless I moved it to the middle. Reproduce code: --------------- // This works. // $reg = "^[[:alnum:[EMAIL PROTECTED]:alnum:]_\.\-]+$"; // This does not work. The only difference // is the order of the last two accepted // characters in the first character class. $reg = "[EMAIL PROTECTED]:alnum:]_\.\-]+$"; var_dump(ereg($reg, '[EMAIL PROTECTED]')); Expected result: ---------------- Does match. Actual result: -------------- Does not match. -- Edit bug report at http://bugs.php.net/?id=41077&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41077&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41077&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41077&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41077&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41077&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41077&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41077&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41077&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41077&r=support Expected behavior: http://bugs.php.net/fix.php?id=41077&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41077&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41077&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41077&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41077&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41077&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41077&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41077&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41077&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41077&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41077&r=mysqlcfg
