Json Serializer with Closure for PHP

Introduction

This repository provides the variables, object and closure serializing and unserializing by integrate two repositories(Zumba\JsonSerializer and laravel/serializable-closure) for PHP.

It still leave the original repo Zumba\JsonSerializer operation and solve it's problem that cannot serialize the closure because the dependency repo SuperClosure\Serializer is no longer maintained.

Simply put, This repository complements the shortcomings of two repositories and provides a complete soluation for PHP Object/Closure serialization.

Installation

How to Use

Serializing Data

You still use the Zumba\JsonSerializer to serialize\unserialize your variables or object, it will be like:

class MyCustomClass {
	public $isItAwesome = true;
	protected $nice = 'very!';
}

$instance = new MyCustomClass();

$serializer = new Zumba\JsonSerializer\JsonSerializer();
$json = $serializer->serialize($instance);
// $json will contain the content {"@type":"MyCustomClass","isItAwesome":true,"nice":"very!"}

$restoredInstance = $serializer->unserialize($json);
// $restoredInstance will be an instance of MyCustomClass

(From Zumba\JsonSerializer)

And the other more operation, refer to Zumba\JsonSerializer.

Serializing Closure

You may serialize your data including the clousre like this:

use Pingyi\JsonSerializer\ClosureSerializer\ClosureSerializer;
use Zumba\JsonSerializer\JsonSerializer;

$outsideData = "Jack";
$toBeSerialized = [
    "name"      => 'N$ck',
    "arrayData" => [1, 2, 3],
    "closure_1"   => fn (string $s = "Hello") => print_r($s . PHP_EOL),
    "closure_2"   => function (string $s = "Hello") use ($outsideData) {
        print_r("{$s} {$outsideData}." . PHP_EOL);
    }
];

$jsonSerializer = new JsonSerializer(new ClosureSerializer());

$serializedData   = $jsonSerializer->serialize($toBeSerialized);
$unserializedData = $jsonSerializer->unserialize($serializedData);

call_user_func($unserializedData["closure_1"]);
call_user_func($unserializedData["closure_2"]);

or your class including closure, like this:

use Pingyi\JsonSerializer\ClosureSerializer\ClosureSerializer;
use Zumba\JsonSerializer\JsonSerializer;
use stdClass;

$toBeSerializedClass = new stdClass();
$toBeSerializedClass->name      = "Mary";
$toBeSerializedClass->arrayData = [1, 2, 3];
$toBeSerializedClass->closure   = function (string $s = "Hello") {
    print_r("{$s}." . PHP_EOL);
};

$jsonSerializer = new JsonSerializer(new ClosureSerializer());

$serializedData   = $jsonSerializer->serialize($toBeSerializedClass);
$unserializedData = $jsonSerializer->unserialize($serializedData);

call_user_func($unserializedData->closure);

Also, you can serialize the simple closure by using the ClosureSerializer, like:

$closure   = function (string $s = "Hello") {
    print_r("{$s}." . PHP_EOL);
};

$closureSerializer = new ClosureSerializer();

$serializedData   = $closureSerializer->serialize($closure);
$unserializedData = $closureSerializer->unserialize($serializedData);

call_user_func($unserializedData);

In addition, you can set your secret key when you construct the ClosureSerializer(), like:

new ClosureSerializer("your secret key");
