How to find poll_id in VK?

Question

PHP

We go to the section for VK developers and there we encounter a problem:
In the list of methods , poll_id is the poll identifier (positive number). Example: 80539252
In the poll widget documentation, poll_id is also the poll ID (only a string). You can get it using the form on the https://vk.com/dev/Poll page or using the "Get code" button in an existing poll. Example: 6564504_c2a6ccb7df15aff473
How can I get the numeric poll_id given the string?

Answer 1

The solution lay on the surface. The first part (before the underscore) of the string version of poll_id is the numeric version.
