History
From Personal Homepage Tools to the World's Most Deployed Language
PHP was created by Rasmus Lerdorf in 1994 as a set of "Personal Home Page" tools — small scripts to track visitors to his online resume. He never intended to build a programming language. But other developers found his tools useful, extended them, rewrote them, and by 1997 PHP had grown into a proper server-side scripting language with a real parser and a growing user base.
The early 2000s brought explosive growth. PHP was easy to install on cheap shared hosting, it embedded naturally inside HTML, and it connected to MySQL databases without friction. This made it the obvious choice for the first generation of web apps — and for the platforms that powered them. WordPress, launched in 2003, bet on PHP. So did Drupal, Joomla, and eventually Facebook, which ran on PHP for years before building a custom solution.
PHP has modernized significantly. PHP 8 brought a JIT compiler, union types, named arguments, and a more expressive language overall. The Laravel framework brought elegance and convention to PHP development that drew back many developers who had moved on. Today PHP is not a legacy curiosity — it's a mature, fast, actively developed language with millions of deployments worldwide.
Why Builders Use It
The WordPress Advantage
WordPress powers over 40% of all websites. For a domain investor, that means an enormous ecosystem of themes, plugins, hosting options, and potential buyers who already know the platform. Building a WordPress site on a good domain — with original content and a clear niche — is one of the most proven paths to creating a sellable developed domain.
Understanding basic PHP opens up WordPress development beyond drag-and-drop builders. You can modify theme templates, write custom plugins, build membership portals, and create tools that don't exist in the plugin marketplace. Even simple PHP knowledge lets you read and edit WordPress code with confidence rather than guessing.
Beyond WordPress, Laravel is one of the most elegant web frameworks in any language. It excels at building content management systems, SaaS applications, and API backends — all common patterns for monetizable built-out domains. AI tools handle Laravel code well, and the framework's documentation is some of the best written in the ecosystem.
