This is my array, and I would like that username is always at the beginning and password is always at the end.

  array(5) {

  [0]=>

  array(8) {

    ["fieldName"]=>

    string(5) "email"

    ["type"]=>

    string(6) "string"

    ["scale"]=>

    int(0)

    ["length"]=>

    int(191)

    ["unique"]=>

    bool(true)

    ["nullable"]=>

    bool(false)

    ["precision"]=>

    int(0)

    ["columnName"]=>

    string(5) "email"

  }

  [1]=>

  array(8) {

    ["fieldName"]=>

    string(8) "isActive"

    ["type"]=>

    string(7) "boolean"

    ["scale"]=>

    int(0)

    ["length"]=>

    NULL

    ["unique"]=>

    bool(false)

    ["nullable"]=>

    bool(false)

    ["precision"]=>

    int(0)

    ["columnName"]=>

    string(9) "is_active"

  }

  [2]=>

  array(8) {

    ["fieldName"]=>

    string(8) "password"

    ["type"]=>

    string(6) "string"

    ["scale"]=>

    int(0)

    ["length"]=>

    int(64)

    ["unique"]=>

    bool(false)

    ["nullable"]=>

    bool(false)

    ["precision"]=>

    int(0)

    ["columnName"]=>

    string(8) "password"

  }

  [3]=>

  array(8) {

    ["fieldName"]=>

    string(8) "username"

    ["type"]=>

    string(6) "string"

    ["scale"]=>

    int(0)

    ["length"]=>

    int(25)

    ["unique"]=>

    bool(true)

    ["nullable"]=>

    bool(false)

    ["precision"]=>

    int(0)

    ["columnName"]=>

    string(8) "username"

  }

  [4]=>

  array(9) {

    ["fieldName"]=>

    string(2) "id"

    ["type"]=>

    string(7) "integer"

    ["scale"]=>

    int(0)

    ["length"]=>

    NULL

    ["unique"]=>

    bool(false)

    ["nullable"]=>

    bool(false)

    ["precision"]=>

    int(0)

    ["id"]=>

    bool(true)

    ["columnName"]=>

    string(2) "id"

  }

}

I could get the array that contains the fieldname password to the end with this code:

$item = $myArray[2];

unset($myArray[2]);

array_push($myArray, $item);

But this is actually not what I am looking for. Because password is not always key 2

This usort will do what you want. It uses a custom sort function that sorts username to the top and password to the bottom of the list. All other values will generally end up in the same order they started in, although that may be unpredictable.

usort($data, function ($a, $b) {  if ($a['fieldName'] == 'username' || $b['fieldName'] == 'password') return -1;

                                  elseif ($a['fieldName'] == 'password' || $b['fieldName'] == 'username') return 1;

                                  else return 0;

                                });

I made small demo on 3v4l.org with only a couple of values from each entry; for that the output result is

Array

(

    [0] => Array

        (

            [fieldName] => username

            [type] => string

        )    

    [1] => Array

        (

            [fieldName] => email

            [type] => string

        )    

    [2] => Array

        (

            [fieldName] => isActive

            [type] => boolean

        )    

    [3] => Array

        (

            [fieldName] => id

            [type] => integer

        )    

    [4] => Array

        (

            [fieldName] => password

            [type] => string

        )    

)

I haven't tested this since I don't want to manually retype your array to real code.

The code uses array_column to make a flat array of fieldname and searches for "password".

If it's found it adds a copy of it last in the array and removes the original then does array_values to reindex the array.

$fieldname = array_column($arr, "fieldName");

$password = array_search("password", $fieldname);

$username = array_search("username", $fieldname);





if($password !== false){

    $arr = $arr[$password];

    unset($arr[$password]);

}

if($username!== false){

    array_unshift($arr, $arr[$username]);

    unset($arr[$username]);

}

$arr = array_values($arr);





var_export($arr);
