Features
--------

[](#features)

- Serialization to JSON
- Unserialization from JSON
- Circular-reference handling
- [Corresponding JavaScript library](https://github.com/maciej-sz/jp-freeze) is available to read serialized data on the browser side

Usage
-----

[](#usage)

This package can be used to serialize and unserialize data objects that contain circular references.

#### Example: basic round-trip

[](#example-basic-round-trip)

```
use MaciejSz\PjFreeze\PjFreeze;

$Freeze = new PjFreeze();

$data = ["foo", "bar", "baz"];

$SerializationResult = $Freeze->serialize($data);
$serializedObj = $SerializationResult->jsonSerialize();

$unserialized = $Freeze->unserialize($serializedObj);
assert($data == $unserialized);
```

#### Example: persisting round-trip

[](#example-persisting-round-trip)

An additional step is required for the serialization result to be persisted: PHP's standard `json_encode()` function has to be called. The `json_encode()` won't produce "*Recursion detected*" error this time.

```
use MaciejSz\PjFreeze\PjFreeze;

$Freeze = new PjFreeze();

$data = ["foo", "bar", "baz"];
$serializedObj = $Freeze->serialize($data)->jsonSerialize();
$serialized_str = json_encode($serializedObj);

file_put_contents("/tmp/data.json", $serialized_str);
// ...
$contents_str = file_get_contents("/tmp/data.json");
$unserialized = $Freeze->unserializeJson($contents_str);
assert($data == $unserialized);
```

#### Example: circular reference

[](#example-circular-reference)

Using only `json_encode()`:

```
// WARNING: this is an example of how NOT to encode circular references
use MaciejSz\PjFreeze\PjFreeze;

$data = new \stdClass();
$data->recursion = $data; // circular reference

$raw_encoded = json_encode($data);
echo json_last_error_msg(); // "Recursion detected"
```

Using `PjFreeze`:

```
use MaciejSz\PjFreeze\PjFreeze;

$data = new \stdClass();
$data->recursion = $data; // circular reference

$Freeze = new PjFreeze();

$serializedObj = $Freeze->serialize($data)->jsonSerialize();
$jp_freeze_encoded = json_encode($serializedObj);
echo json_last_error_msg(); // "No error"

$unserializedObj = json_decode($jp_freeze_encoded);
$unserialized = $Freeze->unserialize($unserializedObj);
assert($unserialized->recursion === $unserialized);
```

Installation
------------

[](#installation)

Via composer:

```
composer require maciej-sz/pj-freeze

```
