Zend replacement in 2.4.6

Question

I have a theme and extensions that use widely the Zend_Json function i.e.for example : window.checkout = getConfig()); ?>; in 2.4.5 I had no problem using this code, in 2.4.6 it throws an exception : " main.CRITICAL: Error: Class "Zend_Json" not found in" I have the laminas package...what can go wrong ? TIA for help

Answer 1

Zend usage deprecated since 2.4.6 Now you can use Laminas. Usage: replace Zend_Json with \Laminas\Json\Json Be sure that you have installed laminas/laminas-serializer

Answer 2

I. Magento 2.4.6 doesn't require laminas/laminas-serializer out-of-the-box. It requires laminas/laminas-json. You can use laminas/laminas-json.

II. But there is a more proper way:

\Magento\Framework\Serialize\Serializer\Json->serialize()
\Magento\Framework\Serialize\Serializer\Json->unserialize()

just to add object in your __construct().

    public function __construct(
        private readonly \Magento\Framework\Serialize\Serializer\Json $jsonSerializer
    ) {
        $string = $this->jsonSerializer->serialize(['data' => 'to_encode']);
    }

Answer 3

You can use like following

Magento 2.4.3
\Zend_Json::decode($infoRequestOption->getData('value'),true);

Magento 2.4.6
\Laminas\Json\Json::decode($infoRequestOption->getData('value'),true);
