PHP array conversion

1 array merge
how to implement it? Thank you!

array(3) {
  [0] => array(7) {
    ["game_name"] => string(18) ""
    ["game_icon"] => string(32) "game_icon_wx0913c2de2ce8376a.png"
    ["id"] => int(1)
    ["gift_name"] => string(15) ""
    ["gift_details"] => string(23) "*5000  *100"
    ["need_score"] => int(30)
    ["gift_type"] => int(2)
  }
  [1] => array(7) {
    ["game_name"] => string(18) ""
    ["game_icon"] => string(32) "game_icon_wx0913c2de2ce8376a.png"
    ["id"] => int(2)
    ["gift_name"] => string(15) ""
    ["gift_details"] => string(25) "*50000  *1000"
    ["need_score"] => int(120)
    ["gift_type"] => int(2)
  }
  [2] => array(7) {
    ["game_name"] => string(18) ""
    ["game_icon"] => string(32) "game_icon_wx945daf05d01dad39.png"
    ["id"] => int(3)
    ["gift_name"] => string(12) ""
    ["gift_details"] => string(8) "*1"
    ["need_score"] => int(50)
    ["gift_type"] => int(1)
  }
}

modify to:

array(3) {
  [0] => array(7) {
    ["game_name"] => string(18) ""
    ["game_icon"] => string(32) "game_icon_wx0913c2de2ce8376a.png"
    ["gift"]=>array(2){
      [0]=>array(5){
        ["id"] => int(1)
        ["gift_name"] => string(15) ""
        ["gift_details"] => string(23) "*5000  *100"
        ["need_score"] => int(30)
        ["gift_type"] => int(2)
      }
      [1]=>array(5){
        ["id"] => int(2)
        ["gift_name"] => string(15) ""
        ["gift_details"] => string(25) "*50000  *1000"
        ["need_score"] => int(120)
        ["gift_type"] => int(2)
      }
    }
  }
  [2] => array(7) {
    ["game_name"] => string(18) ""
    ["game_icon"] => string(32) "game_icon_wx945daf05d01dad39.png"
    ["gift"]=>array(2){
      [0]=>array(){
        ["id"] => int(3)
        ["gift_name"] => string(12) ""
        ["gift_details"] => string(8) "*1"
        ["need_score"] => int(50)
        ["gift_type"] => int(1)
      }
    }
  }
}

array code, I don"t bother to write it. Give me a JSON array! Convenient installation and replacement test

[
{
"game_name": "",
"game_icon": "game_icon_wx0913c2de2ce8376a.png",
"id": 1,
"gift_name": "",
"gift_details": "*5000 *100",
"need_score": 30,
"gift_type": 2
},
{
"game_name": "",
"game_icon": "game_icon_wx0913c2de2ce8376a.png",
"id": 2,
"gift_name": "",
"gift_details": "*50000 *1000",
