kudrmichal/serializer 是适用于PHP 8.0+的PHP对象xml/json映射器

需求

kudrmichal/serializer 需要 PHP 8.0 或更高版本。

安装

要安装 kudrmichal/serializer 的最新版本，请使用 Composer。

$ composer require kudrmichal/serializer

JSON使用

让我们创建两个测试类

use KudrMichal\Serializer\Json\Metadata as JSON;

class Test
{
    public function __construct(
        #[JSON\Property(name:"testInt")] 
        private int $testInteger,
        #[JSON\Property] 
        private string $testString,
        #[JSON\Property]
        private bool $testBoolean,
        #[JSON\PropertyArray]
        private array $testArray,		
        #[JSON\Property]
        private TestObject $testObject,
        #[JSON\PropertyArray(type:TestObject::class)]
        private array $testObjectsArray,
    ) {}

    //getters, setters, etc.
}


class TestObject
{
    public function __construct(
        #[JSON\Property] private int $testObjectInt, 
        #[JSON\Property] private string $testObjectString, 
        #[JSON\Property] private bool $testObjectBoolean, 
        #[JSON\PropertyArray] private array $testObjectArray
    ) {}
    
    //getters, setters, etc.
}

将JSON字符串序列化为PHP对象

$json = <<<JSON
{
  "testInt": 10,
  "testString": "string test",
  "testBoolean": true,
  "testArray": [1,2,3,4],
  "testObject": {
    "testObjectInt": 11,
    "testObjectString": "object string test",
    "testObjectBoolean": false,
    "testObjectArray": [5,6,7,8]
  },
  "testObjectsArray": [
    {
      "testObjectInt": 12,
      "testObjectString": "array object string test",
      "testObjectBoolean": false,
      "testObjectArray": [10,11,12]
    },
    {
      "testObjectInt": 13,
      "testObjectString": "array object string test 2",
      "testObjectBoolean": true,
      "testObjectArray": [13,14,15]
    }
  ]
}
JSON;	

$deserializer = new Deserializer();
$test = $deserializer->deserialize(Test::class, $json);

$test instanceof Test // true

将PHP对象序列化为JSON字符串

$object = new Test(
    10,
    'string test',
    TRUE,
    [1,2,3,4],
    [4,3,2,1],
    new TestObject(11, 'object string test', FALSE, [5,6,7,8]),
    [
        new TestObject(12, "array object string test", false, [10,11,12]),
        new TestObject(13, "array object string test 2", true, [13,14,15]),
    ],
);

$serializer = new \KudrMichal\Serializer\Json\Serializer();
$json = $serializer->serialize($object);

XML使用

让我们再创建两个测试类

use KudrMichal\Serializer\Unit\Xml\Classes\TestObject;
use KudrMichal\Serializer\Xml\Metadata as XML;

#[XML\Document(name:"test")]
class Test
{
    public function __construct(
        #[XML\Element(name:"testInteger")]
        private int $testInt,
        #[XML\Attribute(name:"testAttributeInt")]
        private int $testAttributeInteger,
        #[XML\Element]
        private string $testString,
        #[XML\Element]
        private bool $testBoolean,
        #[XML\Element(dateFormat: "Y-m-d")]
        private \DateTimeImmutable $testDate,
        #[XML\Elements(name: "testArrayItem", type: "int")]
        private array $testArray,
        #[XML\ElementArray(type:"int", itemName: "testNestedArrayItem")]
        private array $testNestedArray,
        #[XML\Element]
        private TestObject $testObject,
        #[XML\ElementArray(type: TestObject::class, itemName: "testObject")]
        private array $testObjectNestedArray
    ) {}
    
    //getters, setters, etc.
}

class TestObject
{
    public function __construct(
        #[XML\Element(name:"testInteger")]
        private int $testObjectInt, 
        #[XML\Attribute(name:"testAttributeInt", ignoreNull: true)]
        private ?int $testObjectAttributeInt = NULL,
        #[XML\Element(ignoreNull: true)] 
        private ?string $testObjectString = NULL
    ) {}

    //getters, setters, etc.
}

将PHP对象序列化为 \DOMDocument

$test = new Test(
    321,
    123,
    '321',
    true,
    new \DateTimeImmutable('2022-02-22'),
    [1,2,3],
    [3,2,1],
    new \KudrMichal\Serializer\Unit\Xml\Classes\TestObject(9, 10, 'test'),
    [
        new \KudrMichal\Serializer\Unit\Xml\Classes\TestObject(5),
        new \KudrMichal\Serializer\Unit\Xml\Classes\TestObject(6, testObjectString: 'true'),
    ]
);

$serializer = new \KudrMichal\Serializer\Xml\Serializer();
$doc = $serializer->serialize($test);

将XML字符串序列化为PHP对象

$xml = <<<XML
<test testAttributeInt="123">
    <testInteger>321</testInteger>
    <testString>321</testString>
    <testBoolean>1</testBoolean>
    <testDate>2022-02-22</testDate>
    <testArrayItem>1</testArrayItem>
    <testArrayItem>2</testArrayItem>
    <testArrayItem>3</testArrayItem>
    <testNestedArray>
        <testNestedArrayItem>3</testNestedArrayItem>
        <testNestedArrayItem>2</testNestedArrayItem>
        <testNestedArrayItem>1</testNestedArrayItem>
    </testNestedArray>
    <testObject testAttributeInt="10">
        <testInteger>9</testInteger>
        <testObjectString>test</testObjectString>
    </testObject>
    <testObjectNestedArray>
        <testObject>
            <testInteger>5</testInteger>
        </testObject>
        <testObject>
            <testInteger>6</testInteger>
            <testObjectString>true</testObjectString>
        </testObject>
    </testObjectNestedArray>
</test>
XML;

$doc = new \DOMDocument();
$doc->loadXML($xml);

$deserializer = new \KudrMichal\Serializer\Xml\Deserializer();
$test = $deserializer->deserialize($doc, \KudrMichal\Serializer\Tests\Unit\Xml\Classes\Test::class);
