你需要
array_multisort
$mylist = array( array('ID' => 1, 'title' => 'Boring Meeting', 'event_type' => 'meeting'), array('ID' => 2, 'title' => 'Find My Stapler', 'event_type' => 'meeting'), array('ID' => 3, 'title' => 'Mario Party', 'event_type' => 'party'), array('ID' => 4, 'title' => 'Duct Tape Party', 'event_type' => 'party'));# get a list of sort columns and their data to pass to array_multisort$sort = array();foreach($mylist as $k=>$v) { $sort['title'][$k] = $v['title']; $sort['event_type'][$k] = $v['event_type'];}# sort by event_type desc and then title ascarray_multisort($sort['event_type'], SORT_DESC, $sort['title'], SORT_ASC,$mylist);从PHP 5.5.0开始：
array_multisort(array_column($mylist, 'event_type'), SORT_DESC, array_column($mylist, 'title'), SORT_ASC, $mylist);
$mylist就是现在：
array ( 0 => array ( 'ID' => 4, 'title' => 'Duct Tape Party', 'event_type' => 'party', ), 1 => array ( 'ID' => 3, 'title' => 'Mario Party', 'event_type' => 'party', ), 2 => array ( 'ID' => 1, 'title' => 'Boring Meeting', 'event_type' => 'meeting', ), 3 => array ( 'ID' => 2, 'title' => 'Find My Stapler', 'event_type' => 'meeting', ),)
