PHP is a popular open-source scripting language used for web development.

Many websites use PHP, including Facebook, because of its easy-to-use nature, including embedded coding for HTML. In general, PHP is regarded as an easy programming language to master for people just starting to learn to program.

As with any programming language, PHP has rules of coding, abbreviations, and algorithms. Learning PHP will be easy or challenging depending on how you approach learning the language itself.

Naturally, if you have a background in programming, you'll probably have a head-start in the process, however there are many resources are available if you are completely new to programming.

Happy Coding!
