PHP is a programming language built for the web. It runs on the server, which means it does its work before a page reaches the visitor’s browser: it reads from the database, checks who is logged in, processes a form, and hands back a finished page. A huge slice of the internet, including WordPress, runs on it.
A simple way to picture PHP is as the kitchen behind a restaurant. The customer never sees it, but it is where the actual cooking happens. When you submit a contact form or log into an account, PHP is often the code in the back receiving the request, doing the work, and sending out the result. This makes it a classic server-side scripting language, the counterpart to the browser-side work usually handled by JavaScript.
Modern PHP looks very different from its early reputation. With a framework like Laravel, it is organised, secure and quick to build with, which is why it stays a sensible choice for everything from small business sites to large platforms handling millions of requests.
Where PHP shows its age is in very high-concurrency, real-time work like chat or live multiplayer, where languages built around long-lived connections often fit better for that specific job. And older PHP codebases that skipped framework structure can become hard to maintain over the years. The fix is rarely a rewrite. It is upgrading to a current version and adopting modern patterns step by step.
At TopDevs we use PHP where it fits the job, especially for content-driven sites and existing platforms, and we keep it modern and well-structured rather than letting it turn into tangled legacy code.
