Hi @user2335065 Thank you for posting your query on Microsoft Q&A and for using Azure services.
My understanding is that you are looking for an equivalent of DynamoDB on Azure as a PHP session handler. First, I would like to apologize for delay in our response.
I suggested using Redis Cache for session handling in your app. To use Azure Cache for Redis as a PHP session cache, specify the connection string to your Azure Cache for Redis instance in session.save_path.
For more information about using Azure Cache for Redis as a PHP session cache with the PhpRedis client, see PHP Session handler.
Please let me know if that answer your question.
Regards,
Oury
