How does the for each know to grab the ID?

So around the end of this video we are told to include the $product_id in the foreach loop.

by adding the "_id" to any name does it know to grab its ID number?

Sorry if I am not typing this in a understandable way. I am just confused on how the server KNOWS to grab the id for the arrays element.

Hi Alexander,

The easier way to understand how foreach works is to look at the documentation.

If you are still having trouble, please post the code you are having issues with and we will help step by step.
