Search engines ignore includes in php?

Question

When it comes to building a web page using other pages iframe is one of the simplest options, but studying on the subject I discovered that they are not recommended because search engines or screen readers ignore their content when they go through the frame.

Another way to build a page using others would be using php include, but then the same question arises: when a search engine or screen reader goes through include, it reads the contents of the page/file or also ignores?

Answer 1

The PHP code is processed on the server. The document that the browser (client) receives is the result of this processing, so the search engines will not know of the existence of include.
