note 85046 added to function.ksort

Be careful when using ksort for mixed type keys!! $a = array( 'first' => true, 0 => 'sally', ); $b = array( 0 => 'sally', 'first' => true, ); ksort($a); ksort($b); var_dump($a); var_dump($b); Output is: array( 0 => 'sally', 'first' => true, ) array( 'first' => true, 0 => 'sally', ) If you want same results for both arrays, use: ksort($a, SORT_STRING); The reason for that lays in the compare mechanism which would normally just typecast 'first' to an integer or 0 to a string when comparing it to each other. So you have to use SORT_STRING, otherwise you would lose information when 'first' is converted to int. ---- Server IP: 217.13.201.10 Probable Submitter: 217.68.166.44 ---- Manual Page -- http://www.php.net/manual/en/function.ksort.php Edit -- https://master.php.net/note/edit/85046 Del: integrated -- https://master.php.net/note/delete/85046/integrated Del: useless -- https://master.php.net/note/delete/85046/useless Del: bad code -- https://master.php.net/note/delete/85046/bad+code Del: spam -- https://master.php.net/note/delete/85046/spam Del: non-english -- https://master.php.net/note/delete/85046/non-english Del: in docs -- https://master.php.net/note/delete/85046/in+docs Del: other reasons-- https://master.php.net/note/delete/85046 Reject -- https://master.php.net/note/reject/85046 Search -- https://master.php.net/manage/user-notes.php
