Parsing PHP generator

Friends, I'm a student in php (online, because in my region there are no courses in php). If anyone can help me with a project and tell me the best tools, thank you. Also if that already exists. I would like to create a php generator. What do I have in mind? have a generic PHP parsing with no data (with variables) to collect information from certain sites (variables will be reported later in an html form) In the html form the user would inform the page where he wants to get the data and the desired variables (in xpath, css, regex or any other possible format) and in the form, and the result (after including the data), clicking Save would generate a php file with the necessary source code and commands. Is it possible?
