Infusionsoft SDK not compatible with PHP 7.2

Hello,
Does anyone have an idea about how to migrate infusionsoft SDK with compatible PHP 7.2?

When we are trying to upgrade PHP version 7.2 into our site we got the errors like as below

Please let me know if anyone has a solution
Thank You

You might try going into the file and global replace http_post_vars with _post or use an earlier version of the api support files that don’t use that compatability hack

I’m currently using PHP 7.2 and haven’t had any issues with their current PHP SDK release. I don’t recognize those files.
