note 83889 added to function.array-merge

I wrote this function to strip one or more arrays to a single one-dimensional array. Keys assigned to individual values are preserved; keys assigned to arrays are not. <?php function array_merge_deep($arr) { // an array-merging function to strip one or more arrays down to a single one dimension array $arr = (array)$arr; $argc = func_num_args(); if ($argc != 1) { $argv = func_get_args(); for ($i = 1; $i < $argc; $i++) $arr = array_merge($arr, (array)$argv[$i]); } $temparr = array(); foreach($arr as $key => $value) { if (is_array($value)) $temparr = array_merge($temparr, array_merge_deep($value)); else $temparr = array_merge($temparr, array($key => $value)); } return $temparr; } ?> Example: <?php $groceries = array("fruits" => array("apples", "bananas", "cherries", "grapes"), "dry goods" => array("bread", "flour", "yeast"), "dairy" => "milk"); $groceries = array_merge_deep($groceries); echo "<pre>"; print_r($groceries); echo "</pre>"; ?> Yields the following: Array ( [0] => apples [1] => bananas [2] => cherries [3] => grapes [4] => bread [5] => flour [6] => yeast [dairy] => milk ) ---- Server IP: 69.147.83.197 Probable Submitter: 99.139.84.133 ---- Manual Page -- http://www.php.net/manual/en/function.array-merge.php Edit -- https://master.php.net/note/edit/83889 Del: integrated -- https://master.php.net/note/delete/83889/integrated Del: useless -- https://master.php.net/note/delete/83889/useless Del: bad code -- https://master.php.net/note/delete/83889/bad+code Del: spam -- https://master.php.net/note/delete/83889/spam Del: non-english -- https://master.php.net/note/delete/83889/non-english Del: in docs -- https://master.php.net/note/delete/83889/in+docs Del: other reasons-- https://master.php.net/note/delete/83889 Reject -- https://master.php.net/note/reject/83889 Search -- https://master.php.net/manage/user-notes.php
