Is it possible to modify PHP scripts with codecanyon.ru?

Question

PHP

I want to buy a PHP script from codecanyon.net and modify it according to my preferences. I learned that there is closed and open code in php. So is it possible to improve? In the sense, is any license for revision suitable in technical terms?

Answer 1

You can’t - they will find, tie you up and cut off your hands.
What does refinement mean? Sell ​​the modified version or use it yourself

Answer 2

See the license under which the files are released.
