將PHP數組轉換為JSON字符串

Question

我有一個看起來像這樣的數組：

Array ( 
       [1] => Laravel 
       [2] => Volta 
       [3] => Web 
       [4] => Design 
       [5] => Development 
      )

現在，我想將此數組轉換為必須如下所示的字符串

data: [{id: 1, text: 'Laravel'},{id: 2, text: 'Volta'},{id: 3, text: 'Web'},...],

Answer 1

使用json_encode

echo json_encode($array);

Answer 2

你可以試試

$data = Array(
        1 => "Laravel",
        2 => "Volta",
        3 => "Web",
        4 => "Design",
        5 => "Development"
);

array_walk($data, function (&$item, $key) {
    $item = array("id"=>$key,"text"=>$item);
});

print(json_encode(array("data"=>array_values($data))));

輸出量

{"data":[{"id":1,"text":"Laravel"},{"id":2,"text":"Volta"},{"id":3,"text":"Web"},{"id":4,"text":"Design"},{"id":5,"text":"Development"}]}

Answer 3

只需使用php的函數json_encode

Answer 4

您可以使用json_encode做到這一點，並可以使用javascript進行剖析以向用戶顯示
