我合并我的数组,然后我想按日期对它们进行排序,但是我的借贷和收款人在日期中具有不同的名称

这是我合并的代码

 $loan = $this->db->get('loans')->result_array();
 $coll = $this->db->get('collectables')->result_array();
 $result = array_merge($loan, $coll);


这是输出

Array
(
[0] => Array
    (
        [loan_id] => 175
        [loan_fullname] => Albano, Zester Quinn
        [loan_amount] => 15000
        [loan_interest] => 2
        [loan_date] => 2017-05-30
        [loan_total_amount] => 15300
        [loan_collectables] => 1
        [loan_user_id] => 30
    )

[1] => Array
    (
        [loan_id] => 176
        [loan_fullname] => Amamio, Alyanna
        [loan_amount] => 15000
        [loan_interest] => 2
        [loan_date] => 2017-05-31
        [loan_total_amount] => 15300
        [loan_collectables] => 2
        [loan_user_id] => 32
    )

[2] => Array
    (
        [coll_id] => 92
        [coll_date] => 2017-05-30
        [coll_amount] => 15300
        [coll_loan_id] => 175
        [coll_user_id] => 30
    )

[3] => Array
    (
        [coll_id] => 93
        [coll_date] => 2017-05-28
        [coll_amount] => 7650
        [coll_loan_id] => 176
        [coll_user_id] => 32
    )

 [4] => Array
    (
        [coll_id] => 94
        [coll_date] => 2017-06-21
        [coll_amount] => 7650
        [coll_loan_id] => 176
        [coll_user_id] => 32
    )
)


但我想按日期对它们进行排序。谢谢

最佳答案

您好,是的,您无法按日期对数组进行排序,您需要使用函数asort(如果要进行升序排序),用户arsort(如果要进行降序排序)。这是使您理解的示例。

$age = array("Peter"=>"2017-05-30", "Ben"=>"2017-01-31", "Joe"=>"2017-05-30");
asort($age);
foreach($age as $x => $x_value) {
    echo "Key=" . $x . ", Value=" . $x_value;
    echo "<br>";
}
