From: thomas dot meike at nic dot at Operating system: Linux Unix Windows PHP version: 5.2.6 PHP Bug Type: Arrays related Bug description: strange behaviour on saving arrays with moved cursors in Session
Description: ------------ you define an array step through ONLY SOME elements using list-each structure stepping through you perform some changes on data finishing the while-structure the array is saved in session let's say, somewhere else in your businesslogic you need these session data once more: you initiate a variable with the recently saved session array the PROBLEM now: the variable is initiated with the array NOT RESETTED as defined in documentation an array assigned to a variable has to be resetted the problem exists also with php version 5.2.5 Reproduce code: --------------- session_start(); $arrL = array("test1","test2","test3","test4","test5","test6","test7","test8","test9","test10"); if(!isset($_SESSION['DATA'])){ $_SESSION['DATA']=$arrL; } $counter = 3; $arrSessData = $_SESSION['DATA']; while((list($index, $value) = each($arrSessData)) && ($counter > 0) ) { $arrSessData[$index] = '_test_' . $value; $counter--; } //store changes in session $_SESSION['DATA']=$arrSessData; //somewhere else within the businesslogic, init local variable and step through $arrSessDataProc = $_SESSION['DATA']; while((list($index, $value) = each($arrSessDataProc)) ){ echo "<br>" . $index . ' ' . $value; } Expected result: ---------------- 0 _test_test1 1 _test_test2 2 _test_test3 3 test4 4 test5 5 test6 6 test7 7 test8 8 test9 9 test10 Actual result: -------------- 4 test5 5 test6 6 test7 7 test8 8 test9 9 test10 -- Edit bug report at http://bugs.php.net/?id=45369&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45369&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45369&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45369&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45369&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45369&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45369&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45369&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45369&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45369&r=support Expected behavior: http://bugs.php.net/fix.php?id=45369&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45369&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45369&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45369&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45369&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45369&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45369&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45369&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45369&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45369&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45369&r=mysqlcfg
