note 76707 added to function.array-filter

Here is my own version of Renee Sarsoo's array_split() function; given an array and a callback it returns two arrays, in which the first contains elements that passed the filter and the second contains elements that didn't. (If no callback is passed, the first array contains the nonempty elements, as you'd get from array_filter() if you don't give it a callback). Array keys are preserved. <?php function partition($input, $callback=null) { static $not_empty=null; if(is_null($not_empty)) $not_empty = create_function('$o', 'return !empty($o);'); if(is_null($callback)) $callback = $not_empty; $true = array_filter($input, $callback); $false = array_diff_key($input, $true); return array($true, $false); } ?> ---- Server IP: 202.89.58.1 Probable Submitter: 60.234.168.92 ---- Manual Page -- http://www.php.net/manual/en/function.array-filter.php Edit -- https://master.php.net/note/edit/76707 Del: integrated -- https://master.php.net/note/delete/76707/integrated Del: useless -- https://master.php.net/note/delete/76707/useless Del: bad code -- https://master.php.net/note/delete/76707/bad+code Del: spam -- https://master.php.net/note/delete/76707/spam Del: non-english -- https://master.php.net/note/delete/76707/non-english Del: in docs -- https://master.php.net/note/delete/76707/in+docs Del: other reasons-- https://master.php.net/note/delete/76707 Reject -- https://master.php.net/note/reject/76707 Search -- https://master.php.net/manage/user-notes.php
