php - 将数组转换为数组

Question

I have an array like below:

array:3 [▼
  "_token" => "hLuF5TLimRRkxRUOeeWoOby7iXLNXU7EiHRmTAso"
  "room_id" => array:3 [▼
    0 => "089a6ca8-26de-3ca2-bbbf-17c410d15266"
    1 => "13c56ac2-6c77-3ca7-b24a-2a70f4f0526c"
    2 => "2d9b7392-aa50-37e4-882a-804affb87223"
  ]
  "new_electric" => array:3 [▼
    0 => "123"
    1 => "234"
    2 => "345"
  ]
]

How can I slice it into new array which like

array:4 [▼
  "_token" => "hLuF5TLimRRkxRUOeeWoOby7iXLNXU7EiHRmTAso"
  "1" => array:2 [▼
    "room_d" => "089a6ca8-26de-3ca2-bbbf-17c410d15266"
    "new_electric => "123"
  ]
  "2" => array:2 [▼
    "room_id" => "13c56ac2-6c77-3ca7-b24a-2a70f4f0526c"
    "new_electric" => "234"
  ]
  "3" => array:2 [▼
    "room_id" => "2d9b7392-aa50-37e4-882a-804affb87223"
    "new_electric" => "345"
      ]
]

I think I need to use an array_push but I don't know how to do that ? Please help.

You have to use foreach

$arr = array(
      "_token" => "hLuF5TLimRRkxRUOeeWoOby7iXLNXU7EiHRmTAso",
      "room_id" => array(
        0 => "089a6ca8-26de-3ca2-bbbf-17c410d15266",
        1 => "13c56ac2-6c77-3ca7-b24a-2a70f4f0526c",
        2 => "2d9b7392-aa50-37e4-882a-804affb87223",
      ),
      "new_electric" => array(
        0 => "123",
        1 => "234",
        2 => "345",
      )
    );

    $final = array();
    $final[ "_token" ] = $arr[ "_token" ];

    foreach( $arr[ "room_id" ] as $key => $value ) {

        $final[ ( $key + 1 ) ] = array(
            "room_id" => $value,
            "new_electric" => $arr[ "new_electric" ][ $key ]
        );

    }

This will result to:

   Array
(
    [_token] => hLuF5TLimRRkxRUOeeWoOby7iXLNXU7EiHRmTAso
    [1] => Array
        (
            [room_id] => 089a6ca8-26de-3ca2-bbbf-17c410d15266
            [new_electric] => 123
        )

    [2] => Array
        (
            [room_id] => 13c56ac2-6c77-3ca7-b24a-2a70f4f0526c
            [new_electric] => 234
        )

    [3] => Array
        (
            [room_id] => 2d9b7392-aa50-37e4-882a-804affb87223
            [new_electric] => 345
        )

)

Note: Use $key + 1 because you want the index to start from 1
