note 115550 added to function.array-multisort

We can do the case insensitive sorting using the flag SORT_FLAG_CASE. So the example #4 can be updated like this $array = array('Alpha', 'atomic', 'Beta', 'bank'); $array_lowercase = array_map('strtolower', $array); array_multisort($array, SORT_ASC, SORT_STRING | SORT_FLAG_CASE); print_r($array); Output Array ( [0] => Alpha [1] => atomic [2] => bank [3] => Beta ) ---- Server IP: 72.52.91.14 Probable Submitter: 180.215.6.210 ---- Manual Page -- http://php.net/manual/en/function.array-multisort.php Edit -- https://master.php.net/note/edit/115550 Del: integrated -- https://master.php.net/note/delete/115550/integrated Del: useless -- https://master.php.net/note/delete/115550/useless Del: bad code -- https://master.php.net/note/delete/115550/bad+code Del: spam -- https://master.php.net/note/delete/115550/spam Del: non-english -- https://master.php.net/note/delete/115550/non-english Del: in docs -- https://master.php.net/note/delete/115550/in+docs Del: other reasons-- https://master.php.net/note/delete/115550 Reject -- https://master.php.net/note/reject/115550 Search -- https://master.php.net/manage/user-notes.php
