From: webmaster at adurosolutions dot com Operating system: CentOs PHP version: 5.2.9 PHP Bug Type: PCRE related Bug description: (?{CODE}) pattern not recognized, won't compile expression
Description: ------------ The (?{CODE}) regular expression has been in Perl since <= 5.005, and the PHP documentation for PCRE says that it's current as of 5.005. This functionality does not appear to be functional in PHP 5.2.9. Reproduce code: --------------- <? $pattern = '/^(?{ $d=0 })(?:\((?{$d++})|\)(?{$d--})(?(?{$d<0})(?!))|(?>[^()]*))*(?(?{$d!=0})(?!))$/'; $pattern_simple = '/^(?{$d=0})\(/'; $subject = '((I)(like(pie))!)'; echo "result: ".preg_match($pattern, $subject)."<br/>"; echo "result_simple: ".preg_match($pattern_simple, $subject)."<br/>"; ?> Expected result: ---------------- I'm not claiming that the regular expressions should produce a match, but they should compile and be evaluated, and thus return either a 0 or a 1. Actual result: -------------- Warning: preg_match() [function.preg-match]: Compilation failed: unrecognized character after (? or (?- at offset 2 in __FILE__ on line __LINE__ -- Edit bug report at http://bugs.php.net/?id=48432&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48432&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48432&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48432&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48432&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48432&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48432&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48432&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48432&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48432&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48432&r=support Expected behavior: http://bugs.php.net/fix.php?id=48432&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48432&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48432&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48432&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48432&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48432&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48432&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48432&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48432&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48432&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48432&r=mysqlcfg
