Question

$res = array:3 [▼
  0 => array:18 [▼
    "id" => 1
    "smval" => "xys"
  ]
  1 => array:18 [▼
    "id" => 3
    "smval" => "asss"

  ]
  2 => array:18 [▼
    "id" => 4
    "smval" => "deg"

  ]
]

期待结果：

{first_id：1，second_i d：3，third_id：4}

我想将此数组转换为object。所以我可以打电话给ajax

{first_id：1，second_i d：3，third_id：4}

Answer 1

使用json_encode将Array转换为Json。

$res = [ 0 => [ "id" => 1, "smval" => "xys" ],
  1 => [ "id" => 3, "smval" => "asss" ],
  2 => [ "id" => 4 , "smval" => "deg" ]
];

$json = json_encode($res);

print_r($json);

您可以使用动态属性来实现：

$ids = new \stdClass(); //Laravel way due to namespacing
//$ids = new stdClass(); //create a generic empty object
$count = 1;

foreach ($res as $key=>$val){
    $ids->{"id".($count++)} = $val["id"]; //assign the property to the object dynamically
}

echo(json_encode($ids));

或者，如果您需要一组特定的名称，可以使用另一个数组作为名称：

$ids = new \stdClass(); //Laravel way due to namespacing
//$ids = new stdClass(); //create a generic empty object
$names = ["name1", "name2", "name3"];
$count = 0;

foreach ($res as $key=>$val){
    $ids->{$names[$count++]} = $val["id"]; //assign the property to the object dynamically based on the names array
}

echo(json_encode($ids));

将数组转换为json对象并在ajax中调用
