Hi Support,

Is CCAvenue payment gateway supports PHP 7.3 version and above because we are facing the issue.
The below function is not working in the latest php 7.3 or higher version.

$encrypted_data=encrypt($merchant_data, $working_key);

The above code is used as per your example code given on your website but not working (https://phppot.com/php/ccavenue-payment-gateway-integration-in-php-website-with-step-by-step-example/)

Nowadays hosting server not offering PHP below then 7.3 so the mcrypt_encrypt() is not working and problems come.

This is our PHP link - https://www.mobileapplications.online/gkca/phpinfo.php

Let me know what is the solution of the above.
