#47235 [NEW]: preg_replace_callback calling a __call returns incorrect values

From: dmsuperman at gmail dot com Operating system: Linux Ubuntu PHP version: 5.2.8 PHP Bug Type: *Regular Expressions Bug description: preg_replace_callback calling a __call returns incorrect values Description: ------------ When combining the use of preg_replace_callback with the __call automagic function, the value returned to the automagic __call function differs from the expected value. It's always wrapped in a single-element single-dimensional array (from what I can tell). The example code with varied results can describe what I mean perfectly. This happens in 5.2.6 and 5.2.8 (I just downloaded the latest version before testing this bug to be sure). Reproduce code: --------------- <?php class my { function doit(){ preg_replace_callback("/(.+)/", "var_dump", "aa"); preg_replace_callback("/(.+)/", array($this, "output"), "aa"); preg_replace_callback("/(.+)/", array($this, "somefunc"), "aa"); } function output($arg){ var_dump($arg); } function __call($func, $arg){ var_dump($arg); } } $obj = new my(); $obj->doit(); ?> Expected result: ---------------- array(2) { [0]=> string(2) "aa" [1]=> string(2) "aa" } array(2) { [0]=> string(2) "aa" [1]=> string(2) "aa" } array(2) { [0]=> string(2) "aa" [1]=> string(2) "aa" } Actual result: -------------- array(2) { [0]=> string(2) "aa" [1]=> string(2) "aa" } array(2) { [0]=> string(2) "aa" [1]=> string(2) "aa" } array(1) { [0]=> array(2) { [0]=> string(2) "aa" [1]=> string(2) "aa" } } -- Edit bug report at http://bugs.php.net/?id=47235&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47235&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47235&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47235&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47235&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47235&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47235&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47235&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47235&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47235&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47235&r=support Expected behavior: http://bugs.php.net/fix.php?id=47235&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47235&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47235&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47235&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47235&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47235&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47235&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47235&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47235&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47235&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47235&r=mysqlcfg
