parse_str() alternative in magento 2

As we know that magento restrict some core PHP functions which we found in MEQP2 which contains the rules.

Let’s start to over come this issue.

As we know Magento 2 is using Zend Framework ther is a class \Zend\Uri\Uri

First initialise Zend Uri in your class constructor.

public function __construct(
        \Zend\Uri\Uri $zendUri
    ) {
        $this->zendUri = $zendUri;
    }

Now set the query string and then get it as array.

$data = $this->getRequest()->getParams();
$this->zendUri->setQuery($data);
$formatedParams = $this->zendUri->getQueryAsArray();
// $formatedParams is an array of query string.

$formatedParams contains an array of your querystring.

print_r($formatedParams)
// Output

Array
(
    [product] => Array
        (
            [1] => Array
                (
                    [name] => Customization
                    [price] => 100
                )

        )

)
