note 88428 added to function.array-keys

Here's a function I needed to collapse an array, in my case from a database query. It takes an array that contains key-value pairs and returns an array where they are actually the key and value. <?php function array_collapse($arr, $x, $y) { $carr = array(); while ($el = current($arr)) { $carr[ $el[$x] ] = $el[$y]; next($arr); } return $carr; } ?> Example usage (pseudo-database code): <?php $query = db_query('SELECT name, value FROM properties'); $result = db_returnAll($query); /* This will return an array like so: [ ['name' -> 'color', 'value' -> 'blue'], ['name' -> 'style', 'value' -> 'wide-format'], ['name' -> 'weight', 'value' -> 3.6], ['name' -> 'name', 'value' -> 'Waerdthing'] ] */ $propArr = array_collapse($result, 'name', 'value'); /* Now this array looks like: [ ['color' -> 'blue'], ['style' -> 'wide-format'], ['weight' -> 3.6], ['name' -> 'Waerdthing'], */ ?> I found this handy for using with json_encode and am using it for my project http://squidby.com ---- Server IP: 64.71.164.2 Probable Submitter: 69.214.9.69 ---- Manual Page -- http://www.php.net/manual/en/function.array-keys.php Edit -- https://master.php.net/note/edit/88428 Del: integrated -- https://master.php.net/note/delete/88428/integrated Del: useless -- https://master.php.net/note/delete/88428/useless Del: bad code -- https://master.php.net/note/delete/88428/bad+code Del: spam -- https://master.php.net/note/delete/88428/spam Del: non-english -- https://master.php.net/note/delete/88428/non-english Del: in docs -- https://master.php.net/note/delete/88428/in+docs Del: other reasons-- https://master.php.net/note/delete/88428 Reject -- https://master.php.net/note/reject/88428 Search -- https://master.php.net/manage/user-notes.php
