我在 PHP 中有三个数组。阵列的示例结构如下所示。我想检查id是否存在于第一个然后值,因为它不应该在任何其他数组中重复。例如,在id为200的记录下面的数组中存在于第一个数组中,然后它再次位于第三个数组中,因此我想要删除 来自第三个阵列的 c0 将有9个这样的数组。什么是动态的方式。
Array
(
[a0] => Array
(
[id] => 100
[Country] => some country
)
[a1] => Array
(
[id] => 200
[Country] => some country
)
)
Array
(
[b0] => Array
(
[id] =>300
[Country] => some country
)
[b1] => Array
(
[id] => 100
[Country] => some country
[city] => some city
)
)
Array
(
[c0] => Array
(
[id] =>200
[Country] => some country
[state] => some state
)
[c1] => Array
(
[id] => 400
[Country] => some country
)
)
