note 92193 added to function.array-slice

Further to taylorbarstow below (for PHP 5), here's a key based slice for PHP 4 : For numerically indexed arrays, you can re-index, as in array_values(array_slice_keys($array,$keys)) <?php // Slice an array based on a set of selection keys function array_slice_keys($array,$keys) { return array_flip(array_intersect(array_flip($array),$keys)); } ?> Example: $array = array('a'=>'A','b'=>'B','c'=>'C',1=>'D',50=>'E'); $keys = array('a','b',50); yields array('a'=>'A','b'=>'B',50=>'E') Example: $array = array('A','B','C','D','E'); $keys = array(0,2,4); Then array_values(array_slice_keys($array,$keys)) yields array('A','C','E') with indices 0,1,2 (and not 0,2,4) ---- Server IP: 64.71.164.2 Probable Submitter: 209.68.185.23 ---- Manual Page -- http://www.php.net/manual/en/function.array-slice.php Edit -- https://master.php.net/note/edit/92193 Del: integrated -- https://master.php.net/note/delete/92193/integrated Del: useless -- https://master.php.net/note/delete/92193/useless Del: bad code -- https://master.php.net/note/delete/92193/bad+code Del: spam -- https://master.php.net/note/delete/92193/spam Del: non-english -- https://master.php.net/note/delete/92193/non-english Del: in docs -- https://master.php.net/note/delete/92193/in+docs Del: other reasons-- https://master.php.net/note/delete/92193 Reject -- https://master.php.net/note/reject/92193 Search -- https://master.php.net/manage/user-notes.php
