如下数组按照sort已经排序，按照降序排序 已完成，现在需要如果sort相同的时候，按照time降序再次排序一下，数组如下
$order = [
[
'order_sn' => '129381283712',
'sort' => '102',
'time' => '1492841339',
],
[
'order_sn' => '129381283712',
'sort' => '102',
'time' => '1492841440',
],
[
'order_sn' => '129381283712',
'sort' => '101',
'time' => '1492841541',
],
[
'order_sn' => '129381283712',
'sort' => '101',
'time' => '1492841642',
],
[
'order_sn' => '129381283712',
'sort' => '100',
'time' => '1492841743',
],
[
'order_sn' => '129381283712',
'sort' => '100',
'time' => '1492841844',
]
];
谁来帮我解决一下
已解决下面是我的方法
$data = array_chaifen($order);
$_order = [];
foreach ($data as $key => $value) {
foreach ($value as $n => $m) {
$_order[] = $m;
}
}
foreach ($_order as $key => $value) {
$_order[$key]['time'] = timeFormat($value['time']);
}
p($_order);
function timeFormat($timeInt,$format='Y-m-d'){
if(empty($timeInt)||!is_numeric($timeInt)||!$timeInt){
return '';
}
$d = (time()-$timeInt);
if($d<0){
return '';
}else{
if($d<60){
return $d.'秒前';
}else{
if($d<3600){
return floor($d/60).'分钟前';
}else{
if($d<86400){
return floor($d/3600).'小时前';
}else{
if($d<604800){//7天内
return floor($d/86400).'天前';
}else{
return date($format,$timeInt);
}
}
}
}
}
}
function array_chaifen ($data)
{
$arr = [];
foreach ($data as $k => $v) {
$arr[$v['sort']][] = $v;
}
$ret = [];
$_data = [];
foreach ($arr as $key => $value) {
foreach ($value as $n => $m) {
$ret[$key][] = $m['time'];
}
$_data[] = array_pauxu($ret[$key], $arr[$key]);
}
return $_data;
}
function array_pauxu ($ret, $arr)
{
array_multisort($ret, SORT_DESC, $arr);
return $arr;
}
谁能帮我优化一下。。。
