note 124151 added to function.array-merge-recursive

walfs version is pretty good, but it always assumes we want numeric keys as numeric keys. There are possibilities where a numeric key is actually a string '123' For that I modified the function so that the last argument is a true switch to turn keys can be numeric on. Default is that keys are all string. <?php function array_merge_recursive_simple() { // croak on not enough arguemnts (we need at least two) if (func_num_args() < 2) { trigger_error(__FUNCTION__ .' needs two or more array arguments', E_USER_WARNING); return; } // default key is not string $key_is_string = false; $arrays = func_get_args(); // if last is not array, then assume it is trigger for key is always string if (!is_array(end($arrays))) { if (array_pop($arrays)) { $key_is_string = true; } } // check that arrays count is at least two, else we don't have enough if (count($arrays) < 2) { trigger_error(__FUNCTION__.' needs two or more array arguments', E_USER_WARNING); return; } $merged = array(); while ($arrays) { $array = array_shift($arrays); if (!is_array($array)) { trigger_error(__FUNCTION__ .' encountered a non array argument', E_USER_WARNING); return; } if (!$array) { continue; } foreach ($array as $key => $value) { if (is_string($key) || $key_is_string === false) { if (is_array($value) && array_key_exists($key, $merged) && is_array($merged[$key])) { $merged[$key] = call_user_func(__FUNCTION__, $merged[$key], $value, $key_is_string); } else { $merged[$key] = $value; } } else { $merged[] = $value; } } } return $merged; } ?> ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.54 (proxied: 122.212.154.178) ---- Manual Page -- http://php.net/manual/en/function.array-merge-recursive.php Edit -- https://master.php.net/note/edit/124151 Del: integrated -- https://master.php.net/note/delete/124151/integrated Del: useless -- https://master.php.net/note/delete/124151/useless Del: bad code -- https://master.php.net/note/delete/124151/bad+code Del: spam -- https://master.php.net/note/delete/124151/spam Del: non-english -- https://master.php.net/note/delete/124151/non-english Del: in docs -- https://master.php.net/note/delete/124151/in+docs Del: other reasons-- https://master.php.net/note/delete/124151 Reject -- https://master.php.net/note/reject/124151 Search -- https://master.php.net/manage/user-notes.php
