note 80227 added to function.array-intersect-key

I have found the following helpful: <?PHP function array_merge_default($default, $data) { $intersect = array_intersect_key($data, $default); //Get data for which a default exists $diff = array_diff_key($default, $data); //Get defaults which are not present in data return $diff + $intersect; //Arrays have different keys, return the union of the two } ?> It's use is like both of the functions it uses, but keeps defaults and _only_ defaults. It's designed for key arrays, and i'm not sure how it will work on numeric indexed arrays. Example: <?PHP $default = array( "one" => 1, "two" => 2 ); $untrusted = array( "one" => 42, "three" => 3 ); var_dump(array_merge_default($default, $untrusted)); array(2) { ["two"]=> int(2) ["one"]=> int(42) } ?> ---- Server IP: 208.69.120.35 Probable Submitter: 24.46.21.192 ---- Manual Page -- http://www.php.net/manual/en/function.array-intersect-key.php Edit -- https://master.php.net/note/edit/80227 Del: integrated -- https://master.php.net/note/delete/80227/integrated Del: useless -- https://master.php.net/note/delete/80227/useless Del: bad code -- https://master.php.net/note/delete/80227/bad+code Del: spam -- https://master.php.net/note/delete/80227/spam Del: non-english -- https://master.php.net/note/delete/80227/non-english Del: in docs -- https://master.php.net/note/delete/80227/in+docs Del: other reasons-- https://master.php.net/note/delete/80227 Reject -- https://master.php.net/note/reject/80227 Search -- https://master.php.net/manage/user-notes.php
