Installation

You can use composer to install this extension.

Just run:

$ composer require dimaskao/library_for_serializing_objects

How to use

General

At first include this library classes:

require_once __DIR__ . '/XXXXX/vendor/autoload.php';

use Dimaskao\Serializer\JSON   //|\
use Dimaskao\Serializer\XML    //|- Choose what you need
use Dimaskao\Serializer\YAML   //|/

Where XXXXX path to library root folder.

If you want to serialize an object, you should create a new JSON, _YAML_ or XML object.

$json = new JSON();
$yaml = new YAML();
$xml = new XML();

Then use ->serialize() method and pass an object to it. This method will return string with serialized object.

$json = new JSON();
$json->serialize($obj);

Field selection

If you do not want to serialize the all object, you can select individual fields. For this pass array in serialize() with name of field.

$json = new JSON();
$json->serialize($obj, ["value1", "value3"]);

Library extension

If you would add new formats, you should create your own class which extends AbstractSerializer.php and implements SerializerInterface.php.

require_once __DIR__ . '/vendor/autoload.php';
use Dimaskao\Serializer\AbstractSerializer;
use Dimaskao\Serializer\SerializerInterface;

class YourFormat extends AbstractSerializer implements SerializerInterface {

}

This class must have a serialize() method. Use $this->get_data() to get all fields in an object.

$elemetn_list - optional array with the fields to get. Watch Field selection.

class YourFormat extends AbstractSerializer implements SerializerInterface {
    public function serialize($obj, $elemetn_list = []){
        $public_value = $this->get_data($obj, $elemetn_list);
    }
}

Then you can do whatever you want with $public_value, for example:

return json_encode($public_value)

Example

Let's see how it works using the YAML example.

//Include library
require_once __DIR__ . '/vendor/autoload.php';

use Dimaskao\Serializer\YAML;

//Creating test class
class Test {

    public $value = "Value";
    public $value1 = "Value1";
    private $value2 = ["Value2.1" => "first", "Value2.2" => 2];
    protected $value3;

    function __construct($item) {
        $this->value3 = $item;
    }
}
//Creating test object
$test = new Test("Value3");

//Creating YAML object
$yaml = new YAML();

//Saving serialized object
$serialized_obj = $yaml->serialize($test, ["value", "value2"]);

//Views results
echo "<pre>";
print_r($serialized_obj);
echo "</pre>";

As a result, we get.

---
value: Value
value2:
  Value2.1: first
  Value2.2: 2
...
