我的PHP返回：

[{"ContentID":"1","con_Model":"CAR_NAME","Picture_path":"localhost\/1.jpg"},{"ContentID":"2","con_Model":"CAR_NAME1","Picture_path":"localhost\/1.jpg"},{"ContentID":"1","con_Model":"CAR_NAME","Picture_path":"http:\/\/10.0.3.2\/1.jpg"}]

和我的PHP代码

<?php
    //$array = array();
    require("config.inc.php");
    $query="SELECT Content.ContentID,Content.con_Model,Picture.Picture_path from Content INNER JOIN Picture ON Content.ContentID = Picture.ContentID LIMIT 25;";
        try {
            $stmt = $db->prepare($query);
            $stmt->execute();
            $array = $stmt->fetchAll(PDO::FETCH_ASSOC);
        }
        catch (PDOException $ex) {
            // For testing, you could use a die and message. 
            //die("Failed to run query: " . $ex->getMessage());

            //or just use this use this one to product JSON data:
            $response["success"] = 0;
            $response["message"] = "Database Error1. Please Try Again!";
            die(json_encode($response));

        }
        //$json_result = array("content" => $array);
            json_encode($array);
            print_r(json_encode($array));
?>

Answer 1

我认为您正在寻找JSON_PRETTY_PRINT选项。

Documentation for json_encode

示例：

echo '<pre>';
echo json_encode($array, JSON_PRETTY_PRINT);
echo '</pre>';

Answer 2

此外，如果要自定义默认的JSON输出，一种方法是创建实现接口 \ JsonSerializable 的类。

这是一个小例子：

<?php
class Contact implements \JsonSerializable
{
    private $id;
    private $name;
    private $mail;

    public function __construct($id, $name, $mail) {
      $this->id = $id;
      $this->name = $name;
      $this->mail = $mail;
    }

    public function jsonSerialize() {
      return [
        'id' => $this->id,
        'name' => utf8_encode($this->name),
        'email' => utf8_encode($this->mail)
      ];
  }
}

$items = array();
$items[]=new Contact('c200', 'Ravi Tamada', 'ravi@gmail.com');
$items[]=new Contact('c201', 'Johnny Dep', 'johnny_depp@gmail.com');
$items[]=new Contact('c202', 'Leonardo Dicaprio', 'leonardo_dicaprio@gmail.com');

$response = array();
$response['contacts'] = $items;

echo json_encode($response , JSON_PRETTY_PRINT);

?>

如何使PHP中的JSON输出更具人性化？
