#35063 [NEW]: key() returns wrong value in function with array passed by reference

From: dave dot newman at codegate dot co dot uk Operating system: Windows XP PHP version: 4CVS-2005-11-02 (CVS) PHP Bug Type: Arrays related Bug description: key() returns wrong value in function with array passed by reference Description: ------------ I call a function with a reference to an array and an object. I then add the object to the end of the array. When I then use end() and key() to get the key of the the object just added to the array key() always returns 0 rather than the actual key value. Reproduce code: --------------- function addToArray(&$array, $obj) { $array[] = $obj; print_r($array); end($array); print 'last key = '.key($array).'<hr/>'; } print '<pre>'; $array = array(); for ($a=0; $a<5; $a++) addToArray($array, array($a=>$a)); print '</pre>'; Expected result: ---------------- I expect it to print to the screen an array dump followed by the last key value in the array 5 times (seperated by <hr>). I add an object to the array each time, so the last key value displayed should go from 0 to 4. Actual result: -------------- the last key value is always 0 rather than the actual last key value. -- Edit bug report at http://bugs.php.net/?id=35063&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=35063&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=35063&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=35063&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=35063&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35063&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35063&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35063&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35063&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35063&r=support Expected behavior: http://bugs.php.net/fix.php?id=35063&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35063&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35063&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35063&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35063&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35063&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35063&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35063&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35063&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35063&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35063&r=mysqlcfg
