How to make DPF in PHP?

Question

PHP

In general, everything I need is already in this (PHP Extension) An example of the code I need using this lib from Chilkat Software. But this extension is paid, maybe someone knows a free analogue or one with the necessary functionality. The second option, can someone tell me how to implement this without third-party libs. For smart people, like "What's the difficulty in buying, etc."? I answer the project is not commercial, but my personal one, this is part of my master's work and there is no point in buying a license for a year, and the price there is clearly not for students.
