note 110801 added to function.usort

This is a simple but effective algo to sort an array with strings which include date data. The newest date is the first in the array. <?php usort($randomarray, function($a,$b) { //e.g. $randomarry[0] == (.)(.)MMDDYY(*.) // -> note that a string can be seen as an array return (($a[6] > $b[6]) ? -1 : (($a[6] < $b[6]) ? 1 : (($a[6] == $b[6]) ? (($a[7] > $b[7]) ? -1 : (($a[7] < $b[7]) ? 1 : (($a[7] == $b[7]) ? (($a[2] > $b[2]) ? -1 : (($a[2] < $b[2]) ? 1 : (($a[2] == $b[2]) ? (($a[3] > $b[3]) ? -1 : (($a[3] < $b[3]) ? 1 : (($a[3] == $b[3]) ? (($a[4] > $b[4]) ? -1 : (($a[4] < $b[4]) ? 1 : (($a[4] == $b[4]) ? (($a[5] > $b[5]) ? -1 : (($a[5] < $b[5]) ? 1 : (($a[5] == $b[5]) ? 0 : 0))) :0))) :0))) :0))):0))):0))); }); ?> just have to modify the places of the datecomponents in the string. ---- Server IP: 87.106.1.137 Probable Submitter: 194.113.59.80 ---- Manual Page -- http://php.net/manual/en/function.usort.php Edit -- https://master.php.net/note/edit/110801 Del: integrated -- https://master.php.net/note/delete/110801/integrated Del: useless -- https://master.php.net/note/delete/110801/useless Del: bad code -- https://master.php.net/note/delete/110801/bad+code Del: spam -- https://master.php.net/note/delete/110801/spam Del: non-english -- https://master.php.net/note/delete/110801/non-english Del: in docs -- https://master.php.net/note/delete/110801/in+docs Del: other reasons-- https://master.php.net/note/delete/110801 Reject -- https://master.php.net/note/reject/110801 Search -- https://master.php.net/manage/user-notes.php
