Split PDF document into pages in browser?

Question

PHP

Goodnight! There is a need to simplify our lives, every day at work we generate a PDF document with 2 types of pages, each of the types has a clear sign individual for the type.
The task is to determine the number of pages that belong to a certain type and display all the numbers on the screen, write to a file, and the ideal option would be to print from the browser.
Where to dig? I only know PHP

The question is kind of tricky.
Working with PDF is one thing. Allocation of pages on signs - another. Printing is the third.
PDF can be made, for example, using wkhtmltopdf - there are bindings for PHP.
Selecting pages by features is purely business logic and it's up to you to decide how to do it.
Printing a PDF is purely a user-invoked action. If you do not make your own PDF viewer like Google Docs, then you will not be able to initialize the print yourself.
For example, in a recent project where I was generating PDF documents, I had two links: PDF and print. The first led to a PDF download, and the second led to the same document, but in the form of HTML (before wkhtmltopdf processing), where printing was initialized using JS.
