What is the best way to receive new messages?

Question

PHP

There is a key with the rights to messages. There is a hosting with php, cron (once a minute). New messages need to be stored in the database.

Answer 1

When making requests through api, we save the id of the last received message in the self-written cache. Next, with each cron call, we get the dialog using messages.getHistory, where start_message_id = message_id_from_cache.
Then we mark the dialog as read (if needed), add the messages to the database, and update our cache.
If interested, I can give my class for working with the VK API. (But it's also easy to google, just made a very easy one for myself)
