我只想从关联数组的所有键中提取重复项。数组结构是:
Array
(
[bank_users] => Array
(
[0] => 8
[1] => 8
[2] => 8
[3] => 28
)
[bank_link] => Array
(
[0] => 8
[1] => 8
[2] => 8
[3] => 28
[4] => 28
[5] => 28
[6] => 28
[7] => 28
[8] => 73
[9] => 73
[10] => 73
)
[banks] => Array
(
[0] => 8
[1] => 28
)
)
现在在这个数组中,我想要一个函数,它应该检查每个键并给我重复项。就像上面的示例一样,结果应该是8和28,因为这些值在所有三个键中都可用。.bank_users、bank_link、银行。请帮助...
