PHP is a general-purpose scripting language most often used for server-side scripting in web development. It works on your web server, unlike client-side languages like JavaScript that run through browsers. Where Javascript can influence how your site looks and behaves, PHP executes tasks in the background. A number of third-party solutions like WordPress and Magento make it easy for the smallest of businesses to create impressive super-sized websites (content creators – bloggers, vloggers, artists, etc., aside).
According to W3Techs, 78.7% of the websites they track make use of PHP. PHP usage is declining, but very, very slowly – as will become clear when we look at the sheer range of essential third-party programs actively using it for databases, content management and eCommerce.
It adds functionality beyond what HTML can offer on a stand-alone basis, allowing you to generate images, PDF files, Flash movies and offering extensive support for databases. It allows the use of procedural and object-oriented programming or both.
It’s been around since 1994, as some of us may recall, “Before the Internet became a passing fad” and when both personal and business-based websites first started becoming popular. Back then, PHP stood for Personal Home Page. Creative, yes?
Since then, PHP has taken on what’s called a recursive initialism, standing for PHP: Hypertext Preprocessor – like the more famous GNU which stands for “GNU’s Not Unix.” More creative, very geeky. As one might guess, it is maintained by The PHP Group.
