数组根据某值排序(array_multisort)

$coupon=array(2) {
[0]=>
array(9) {
[“id”]=>
string(1) “2”
[“money”]=>
string(5) “10.00”
[“condition”]=>
string(6) “200.00”
[“use_start_time”]=>
string(10) “1539761670”
[“use_end_time”]=>
string(10) “1540483299”
}
[1]=>
array(9) {
[“id”]=>
string(1) “1”
[“money”]=>
string(4) “5.00”
[“condition”]=>
string(6) “100.00”
[“use_start_time”]=>
string(10) “1539761670”
[“use_end_time”]=>
string(10) “1540483288”
}
}

$score = [];

foreach ($coupon as $key => $value) {

$score[$key] = $value['use_end_time'];

}
使用函数array_multisort对数组某个值进行排序，不明白可以查看手册
array_multisort($score, SORT_DESC, $coupon);

var_dump($coupon); 打印出根据某个值进行排序的数组
