I have a array of $users[0]['name'] = "abc" $users[0]['age'] = "12" $users[0]['sex'] = "M"; $users[1]['name'] = "xyz" $users[1]['age'] = "15" $users[1]['sex'] = "M"; $users[2]['name'] = "pqr" $users[2]['age'] = "16" $users[2]['sex'] = "F"; Now I have to sort in on age or 'sex', Quote Link to comment Share on other sites More sharing options...
Adam Posted October 4, 2010 Share Posted October 4, 2010 Use usort to define a function that will perform the sorting logic: function sortByAge($a, $b){ if ($a['age'] == $b['age']) { return 0; } return ($a['age'] < $b['age']) ? -1 : 1;}usort($users, 'sortByAge'); Quote Link to comment Share on other sites More sharing options...
