ID: 64027 Comment by: matthew dot vince at gmail dot com Reported by: mfuhrman at enetarch dot net Summary: ForEach fails to add new key/value pairs Status: Open Type: Bug Package: Scripting Engine problem Operating System: Linux svm0907pdv 2.6.18-308.8.2. PHP Version: 5.3Git-2013-01-18 (snap) Block user comment: N Private report: N New Comment: This is expected behavior. To modify values using a foreach loop, you need to assign by reference, as explained in the foreach documentation: foreach ($aryJunk AS &$sub) $sub ["munch"] = "junk"; http://php.net/manual/en/control-structures.foreach.php Previous Comments: ------------------------------------------------------------------------ [2013-01-18 20:13:51] mfuhrman at enetarch dot net Description: ------------ using PHP Version 5.3.3, Build Date Jun 25 2012 04:51:11 In testing updating nested arrays, I'm finding the that the results of an array is not updated, since the variable used to point to that portion of the array seems to be a copy of the data and not a direct reference to the data. Below is an array of arrays. In the for loop, $sub points to $aryJunk's elements .. 0 .. 4 respectively. When $sub has a new key value pair added, ex. "munch" => "junk", this value only exists as long as $sub exists in the for loop. Outside that loop, the key value pair are lost. It is my understanding that this key value pair should not be lost. Or, at least I cannot find an example that says definitively one way or the other. Please test to see if this issue still exists in the latest version of PHP, and determine the next steps to resolution. Michael J.
