Test script: --------------- preg_match( '/^([^<]+)(?:<([^>]+)>)*$/', 'main<subkey><nothersub><onemore>', $keys ); var_dump($keys); Expected result: ---------------- array( 'main<subkey><nothersub><onemore>', 'main', 'subkey', 'nothersub', 'onemore' ) Actual result: -------------- array( 'main<subkey><nothersub><onemore>', 'main', 'onemore' ) -- Edit bug report at https://bugs.php.net/bug.php?id=73236&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73236&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73236&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73236&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73236&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73236&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73236&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73236&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73236&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73236&r=support Expected behavior: https://bugs.php.net/fix.php?id=73236&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73236&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73236&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73236&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73236&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73236&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73236&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73236&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73236&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73236&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73236&r=mysqlcfg
