note 111943 added to function.array-chunk

array_chunk is great for breaking something into rows of n cells that should be read from left-to-right, top-to-bottom. If you want to transpose it (that is, read from top-to-bottom, left-to-right), you can use the following (keys are not preserved): <?php $a = [1,2,3,4,5,6,7,8,9]; $a = call_user_func_array('array_map', array_merge(null, array_chunk($a, 3))); # $a = [[1,4,7],[2,5,8],[3,6,9]] ?> ---- Server IP: 69.147.83.199 Probable Submitter: 75.70.34.207 ---- Manual Page -- http://php.net/manual/en/function.array-chunk.php Edit -- https://master.php.net/note/edit/111943 Del: integrated -- https://master.php.net/note/delete/111943/integrated Del: useless -- https://master.php.net/note/delete/111943/useless Del: bad code -- https://master.php.net/note/delete/111943/bad+code Del: spam -- https://master.php.net/note/delete/111943/spam Del: non-english -- https://master.php.net/note/delete/111943/non-english Del: in docs -- https://master.php.net/note/delete/111943/in+docs Del: other reasons-- https://master.php.net/note/delete/111943 Reject -- https://master.php.net/note/reject/111943 Search -- https://master.php.net/manage/user-notes.php
