Alongside Python and JavaScript, PHP is one of the most popular server-side web programming languages. Popular web platforms such as content management systems WordPress, Joomla! and TYPO3 are built on the language. MediaWiki – the software that powers Wikipedia, the online learning platform Moodle and many other well-known and popular web-based systems are also written in PHP.
Even though the scripting language used to have a somewhat dubious reputation among developers, the PHP basics are easy to learn. Building a website in PHP is quite fun. You learn a lot about how the ubiquitous client-server applications work and what a website is made of.
