如何使数组键唯一？
我试过A PHP Error was encountered
Severity: Notice
Message: Array to string conversion
Filename: models/mdashboard.php
Line Number: 115
，但它会抛出：
Array
(
[100053] => 100053
[100072] => 100072
[100054] => 100054
[100055] => Array
(
[100056] => Array
(
[100057] => 100057
[100058] => 100058
[100059] => 100059
[100060] => 100060
[100071] => 100071
)
[100061] => Array

[100063] => 100063
[100062] => Array

[100067] => 100067
[100068] => 100068
[100069] => 100069
[100070] => 100070
)
[100064] => 100064
)
)
)
[100056] => Array
(
[100057] => 100057
[100058] => 100058
[100059] => 100059
[100060] => 100060
[100071] => 100071

[100066] => Array
(
[100067] => 100067
[100068] => 100068
[100069] => 100069
[100070] => 100070
)
[100064] => 100064
)
)
[100062] => Array
(
[100065] => 100065
[100066] => Array
(
[100067] => 100067
[100068] => 100068
[100069] => 100069
[100070] => 100070
)
[100064] => 100064
)
[100066] => Array
(
[100067] => 100067
[100068] => 100068
[100069] => 100069
[100070] => 100070
)
)
这是数组：
