You can install the package via composer require command:

composer require jeurboy/object-field-selector

Or simply add it to your composer.json dependences and run composer update:

"require": {
    "jeurboy/object-field-selector": "*"
}

Usage

For simple usage. Just create returned schema and send to DataParser;

    $parser = new Jeurboy\SimpleObjectConverter\SchemaParser();
    $parser->addSchema("test1");
    $token = $parser->getParsedSchema();

    $data = [
        'test1' => "11234",
        'test2' => "22222"
    ];

    $DataParser = new Jeurboy\SimpleObjectConverter\DataParser();
    $return = $DataParser->getOutput($data, $token);
    print_r($return);

You will see following result.

Array
(
    [test1] => 11234
)

If you have nested Array just pass .(Dot) in your schema.

    $parser = new Jeurboy\SimpleObjectConverter\SchemaParser();
    $parser->addSchema("test1.eee");
    $token = $parser->getParsedSchema();

    $data = [
        'test1' => [
            'eee' => "hello holy",
        ]
    ];

    $DataParser = new Jeurboy\SimpleObjectConverter\DataParser();
    $return = $DataParser->getOutput($data, $token);
    print_r($return);

You will get result array like this.

Array
(
    [test1] => Array
        (
            [eee] => hello holy
        )
)

If there are multiple field inside input array, use comma(,) to define more fields.

    $parser = new Jeurboy\SimpleObjectConverter\SchemaParser();
    $parser->addSchema("test1");
    $token = $parser->getParsedSchema();

    $data = [
        'test1' => [
            'eee' => "hello holy",
            'fff' => "hello holy",
        ]
    ];

    $DataParser = new Jeurboy\SimpleObjectConverter\DataParser();
    $return = $DataParser->getOutput($data, $token);
    print_r($return);

You will see the result has multiple field returned.

Array
(
    [test1] => Array
        (
            [eee] => hello holy
            [fff] => hello holy
        )

)

The library also support object inside sequencial array.

    $parser = new Jeurboy\SimpleObjectConverter\SchemaParser();
    $parser->addSchema("test1.hello");
    $token = $parser->getParsedSchema();

    $data = [
        'test1' => [
            [
                "hello" => "world1",
                "ok"    => "google1",
            ],[
                "hello" => "world2",
                "ok"    => "google2",
            ],
        ]
    ];
    $DataParser = new Jeurboy\SimpleObjectConverter\DataParser();
    $return = $DataParser->getOutput($data, $token);
    print_r($return);

Result is

Array
(
    [test1] => Array
        (
            [0] => Array
                (
                    [hello] => world1
                )

            [1] => Array
                (
                    [hello] => world2
                )

        )

)

You can see all test case in example/example.php files.
