What is PHP?
PHP is a popular open-source scripting language that enables developers to create dynamic websites. PHP is used to create simple scripts and databases, as well as more complex applications.

This method uses the SimpleScraper library to extract data from a website. This library is easy to use and provides many options for scraping data.
To use this method, you first need to install the SimpleScraper library. You can download the library from www.simplescraper.org .
