处理后的数组

Array

(

[1] => Array

(

[uid] => 1

[price] => 85.00

[earnings] => 40.00

)

[8] => Array

(

[uid] => 8

[price] => 56.00

[earnings] => 31.00

)

[15] => Array

(

[uid] => 15

[price] => 168

[earnings] => 62

)

[21] => Array

(

[uid] => 21

[price] => 300

[earnings] => 120

)

[231] => Array

(

[uid] => 231

[price] => 60.00

[earnings] => 35.00

)

)

备注：

1、 如果需要处理的数组有空值，则用

$orderWeek =array_filter($orderWeek);

2、 如果想要给所得数组的键从0开始

$orderWeek =array_values($orderWeek);
