Question

我的第一个数组已按名称排序，但我想用位置对其进行排序，我试过的是这里，数组前的数组

    Array
(
    [0] => Array
        (
            [name] => admin
            [designation] => admin
            [email] => admin@admin
            [phone] => 999777788
            [ext] => 67767
            [position] => 1
            [image] =>
        )

    [1] => Array
        (
            [name] => ATeam
            [designation] => Manager
            [email] => service@mail.com
            [phone] => 
            [ext] => 777
            [position] => 3
            [image] => 
        )

    [2] => Array
        (
            [name] => BTeam
            [designation] => Manager
            [email] =>g@mail.co.in
            [phone] => 
            [ext] => 
            [position] => 4
            [image] => 
        )

    [3] => Array
        (
            [name] => hi team
            [designation] => new
            [email] => abc
            [phone] => 3333
            [ext] => 333
            [position] => 10
            [image] =>
        )
[4] => Array
    (
        [name] => new team
        [designation] => maneger
        [email] => mg@g
        [phone] => 445567676
        [ext] => ext
        [position] => 10
        [image] => 
    )

）

应用于数组的

usort函数是：

usort($a_teams,function($a,$b){
          if($a['position'] == '') return 1;
          if($b['position'] == '') return -1;
          return $a['position']-$b['position'];
        });

结果数组是：

Array
(
    [0] => Array
        (
            [name] => admin
            [designation] => admin
            [email] => admin@admin
            [phone] => 999777788
            [ext] => 67767
            [position] => 1
            [image] => 
        )

    [1] => Array
        (
            [name] => ATeam
            [designation] => Manager
            [email] => service@mail.com
            [phone] => 
            [ext] => 777
            [position] => 3
            [image] =>
        )

    [2] => Array
        (
            [name] => BTeam
            [designation] => Manager
            [email] => g@mail.co.in
            [phone] => 
            [ext] => 
            [position] => 4
            [image] => 
        )

    [3] => Array
        (
            [name] => new team
            [designation] => maneger
            [email] => mg@g
            [phone] => 445567676
            [ext] => ext
            [position] => 10
            [image] => 
        )

    [4] => Array
        (
            [name] => hi team
            [designation] => new
            [email] => abc
            [phone] => 3333
            [ext] => 333
            [position] => 10
            [image] => 
        )

)

但问题是当name相同时positions的字母顺序没有按正确顺序排列

Answer 1

更改了按位置和名称排序的usort函数：

 usort($a_teams,function($a,$b){
if ($a["position"]==$b["position"]){
    return strcmp($a["name"], $b["name"]);
}     
return ($a["position"]<$b["position"])?-1:1;

}）;

Answer 2

更改了按位置和名称排序的usort函数：

usort($a_specials,function($a,$b){
    if($a['position'] == '') return 1;
    if($b['position'] == '') return -1;
    if($a['position'] == $b['position'])
        return strnatcmp($a['title'],$b['title']);
    return $a['position']-$b['position'];

}）;
