PHP Version: 5.3Git-2013-01-18 (snap) Block user comment: N Private report: N New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. Previous Comments: ------------------------------------------------------------------------ [2013-01-18 22:00:06] matthew dot vince at gmail dot com 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 ------------------------------------------------------------------------ [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. Fuhrman [email protected] skype ENetArch Test script: --------------- $aryJunk = Array ( 0 => array(), 1 => array(), 2 => array(), 3 => array(), 4 => array(), ); // fails foreach ($aryJunk AS $sub) $sub ["munch"] = "junk"; print_r ($aryJunk); // works for ($t=0; $t < count ($aryJunk); $t++) $aryJunk[$t] ["munch"] = "junk"; print_r ($aryJunk); Expected result: ---------------- Array ( [0] => Array ( [munch] => junk ) [1] => Array ( [munch] => junk ) [2] => Array ( [munch] => junk ) [3] => Array ( [munch] => junk ) [4] => Array ( [munch] => junk ) ) Actual result: -------------- Array ( [0] => Array ( ) [1] => Array ( ) [2] => Array ( ) [3] => Array ( ) [4] => Array ( ) ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64027&edit=1
