取消设置多维数组中的重复项[重复]

Question

任何人都可以提供帮助。我想在下面的数组中消除 mcs_client_ec_no 上的重复项，但不知道如何。

Array
(

[1] => Array
    (
        [mps_client_ec_no] => REG5
        [mcs_client_ec_no] => GL98888
        [mps_school_id] => 6
        [mcs_school_id] => 6
    )

[2] => Array
    (
        [mps_client_ec_no] => TAS4752
        [mcs_client_ec_no] => ALF1252
        [mps_school_id] => 14
        [mcs_school_id] => 14
    )

[3] => Array
    (
        [mps_client_ec_no] => MAP002
        [mcs_client_ec_no] => ALF1252
        [mps_school_id] => 14
        [mcs_school_id] => 14
    )

)

Answer 1

试试这个

$u = array(0=>array("mcs_client_ec_no" => GL98888,"mps_school_id" => 14),1=>array("mcs_client_ec_no" => GL98888,"mps_school_id" => 154)); 

array_unique($u);
