ID: 65452 Updated by: requi...@php.net Reported by: philippe at kinhelios dot com Summary: Change value in array -Status: Open +Status: Not a bug Type: Bug Package: *General Issues Operating System: Linux web1106.90.ha.ovh.net 3.2. PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The reference persists even after the loop finishes. In the second loop, foreach will assign values to $localValue... which is still a reference to the last element in $arrayOne. The net effect is the second-to-last element overwrites the last element. (Try with three or more items in $arrayOne.) Solution: unset($localValue) after the first loop (best), or don't use it as a reference and update $arrayOne using the $localKey, or use a different variable in the second loop, or use references in the second loop.

Loop to change the values in an array by reference and then another loop but same variable name, the initial array is modified again. [translate by http://www.bing.com/translator/] Test script: --------------- <?php $arrayOne = array( 'key1' => array('k1' => 'val_key1_k1'), 'key2' => array('k1' => 'val_key2_k1') ); foreach ($arrayOne as $localKey => &$localValue) // character & $localValue['k1'] .= '_add'; // ----- print_r($arrayOne); $counter = 0; foreach ($arrayOne as $k => $localValue) // same name of variable "$localValue", but local $counter++; print_r($arrayOne); // is the same array ? => NO ! ?> Expected result: ---------------- Array ( [key1] => Array ( [k1] => val_key1_k1_add ) [key2] => Array ( [k1] => val_key2_k1_add ) ) Actual result: -------------- Array ( [key1] => Array ( [k1] => val_key1_k1_add ) [key2] => Array ( [k1] => val_key1_k1_add // Hey! My value changed here ! ) ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65452&edit=1
