我一直在努力尝试用"user_likes"answers"created_time"在PHP中对这个数组进行排序。我看了一些关于Stackoverflow的例子，但找不出正确的语法。我希望订单从最多的"user_likes"开始，然后是"created_time"，不确定这是否可能。我一直在尝试array_multissort，但没有成功。

$results是上面的数组，请尝试
usort($results, function($a, $b){
//check case for same number of user likes
if ($a['user_likes']['user_likes'] == $b['user_likes']['user_likes']){
if (strtotime($a['taskuser']['created_time']) == strtotime($b['taskuser']['created_time'])){
return 0;
} else if (strtotime($a['taskuser']['created_time']) < strtotime($b['taskuser']['created_time'])){
return 1;
} else {
return -1;
}
} else if ($a['user_likes']['user_likes'] < $b['user_likes']['user_likes']){
return 1;
} else {
return -1;
}
});
您需要usort。让回调比较user_likes，然后比较created_time。
