是否可以基于特定对象属性计数数组？
[0] => stdClass Object
(
[ID] => 12345
[Name] => TEST 1
[position] => POS 1
[2023-02-01] => 22:00 - 06:00
[2023-02-02] => REST DAY
[2023-02-03] => 14:00 - 22:00
[2023-02-04] => 14:00 - 22:00
[2023-02-05] => 14:00 - 22:00
[2023-02-06] => 22:00 - 06:00
[2023-02-07] => REST DAY
[2023-02-08] => 14:00 - 22:00
[2023-02-09] => 22:00 - 06:00
[2023-02-10] => DAY OFF
[2023-02-11] => 14:00 - 22:00
[2023-02-12] => -
[2023-02-13] => -
[2023-02-14] => -
[2023-02-15] => -
)
[1] => stdClass Object
(

[position] => POS 2
[2023-02-01] => 06:00 - 14:00

我一直在尝试使用过滤器，但由于版本是5.3，所以它不适用。我也没有使用过PHP，所以语法很难掌握。请注意，这是一个遗留系统。
