note 104771 added to function.array-merge

I'm sorry, but I've not found on this page a function that would properly merge two arrays while overwriting numeric values. Considering two arrays: $test1 = array(array('a','b','c'), 'a', 'b'); $test2 = array(array('d','e'), 'c'); while using overwrite merge you would expect the result to be an array: $test3 = array(array('d','e'), 'c', 'b'); However most of the functions will result with this array: $test4 = array(array('d','e','c'), 'c', 'b'); So, here's a function to do that: function array_merge_overwrite(array &$array1, array $array2 = NULL) { $flag = true; foreach (array_keys($array2) as $key) { if (isset($array2[$key]) && is_array($array2[$key])) { if (isset($array1[$key]) && is_array($array1[$key])) array_merge_overwrite($array1[$key], $array2[$key]); else $array1[$key] = $array2[$key]; $flag = false; } } if ($flag == true) $array1 = $array2; } ---- Server IP: 87.124.126.127 Probable Submitter: 86.164.250.28 (proxied: 86.164.250.28) ---- Manual Page -- http://www.php.net/manual/en/function.array-merge.php Edit -- https://master.php.net/note/edit/104771 Del: integrated -- https://master.php.net/note/delete/104771/integrated Del: useless -- https://master.php.net/note/delete/104771/useless Del: bad code -- https://master.php.net/note/delete/104771/bad+code Del: spam -- https://master.php.net/note/delete/104771/spam Del: non-english -- https://master.php.net/note/delete/104771/non-english Del: in docs -- https://master.php.net/note/delete/104771/in+docs Del: other reasons-- https://master.php.net/note/delete/104771 Reject -- https://master.php.net/note/reject/104771 Search -- https://master.php.net/manage/user-notes.php
