json_decode到自定义类

不会自动发生。但你可以用老式的路线来做。

$data = json_decode($json, true);

$class = new Whatever();
foreach ($data as $key => $value) $class->{$key} = $value;

或者，您可以使其更加自动化：

class Whatever {
    public function set($data) {
        foreach ($data AS $key => $value) $this->{$key} = $value;
    }
}

$class = new Whatever();
$class->set($data);

编辑：变得更花哨一点：

class JSONObject {
    public function __construct($json = false) {
        if ($json) $this->set(json_decode($json, true));
    }

    public function set($data) {
        foreach ($data AS $key => $value) {
            if (is_array($value)) {
                $sub = new JSONObject;
                $sub->set($value);
                $value = $sub;
            }
            $this->{$key} = $value;
        }
    }
}

// These next steps aren't necessary. I'm just prepping test data.
$data = array(
    "this" => "that",
    "what" => "who",
    "how" => "dy",
    "multi" => array(
        "more" => "stuff"
    )
);
$jsonString = json_encode($data);

// Here's the sweetness.
$class = new JSONObject($jsonString);
print_r($class);

我们构建了JsonMapper来自动将JSON对象映射到我们自己的模型类上。它适用于嵌套/子对象。

它仅依赖于文档块类型信息进行映射，大多数类属性无论如何都具有这些信息：

<?php
$mapper = new JsonMapper();
$contactObject = $mapper->map(
    json_decode(file_get_contents('http://example.org/contact.json')),
    new Contact()
);
?>
