这是我的数组的 print_r 输出:
Array
(
[0] => stdClass Object
(
[itemId] => 560639000019
[name] => Item no1
[code] => 00001
[qty] => 5
[id] => 2
)
[1] => stdClass Object
(
[itemId] => 470639763471
[name] => Second item
[code] => 76347
[qty] => 9
[id] => 4
)
[2] => stdClass Object
(
[itemId] => 56939399632
[name] => Item no 3
[code] => 39963
[qty] => 6
[id] => 7
)
)
如何找到具有 [id] => 4 的对象索引以便将其从数组中删除?
