note 71647 added to function.array-merge-recursive

Hi all, Here is a function array_merge_recursive_unique which override values, but walk recursivly arrays and works for unlimited number of arrays. (i posted a previous version which had a bug in recursion). <?php // array_merge_recursive which override value with next value. function array_merge_recursive_unique ($array0, $array1) { $arrays = func_get_args (); $remains = $arrays; // We walk through each arrays and put value in the results (without // considering previous value). $result = array (); // loop available array foreach ($arrays as $array) { // The first remaining array is $array. We are processing it. So // we remove it from remaing arrays. array_shift ($remains); // We don't care non array param, like array_merge since PHP 5.0. if (is_array ($array)) { // Loop values foreach ($array as $key => $value) { if (is_array ($value)) { // we gather all remaining arrays that have such key available $args = array (); foreach ($remains as $remain) { if (array_key_exists ($key, $remain)) { array_push ($args, $remain[$key]); } } if (count ($args) > 2) { // put the recursion $result[$key] = call_user_func_array (__FUNCTION__, $args); } else { $result[$key] = $value; } } else { // simply put the value $result[$key] = $value; } } } } return $result; } ?> Enjoy :D ---- Server IP: 217.174.203.10 Probable Submitter: 82.243.217.90 ---- Manual Page -- http://www.php.net/manual/en/function.array-merge-recursive.php Edit -- https://master.php.net/note/edit/71647 Del: integrated -- https://master.php.net/note/delete/71647/integrated Del: useless -- https://master.php.net/note/delete/71647/useless Del: bad code -- https://master.php.net/note/delete/71647/bad+code Del: spam -- https://master.php.net/note/delete/71647/spam Del: non-english -- https://master.php.net/note/delete/71647/non-english Del: in docs -- https://master.php.net/note/delete/71647/in+docs Del: other reasons-- https://master.php.net/note/delete/71647 Reject -- https://master.php.net/note/reject/71647 Search -- https://master.php.net/manage/user-notes.php
