PHP Load Testing: How to Load Test PHP Applications
PHP powers roughly 77% of all websites with a known server-side language — yet most PHP developers ship code without ever running a load test. The app works fine in development, handles a handful of users on staging, and then crumbles when real traffic arrives. Load testing catches that gap before your users do: it verifies that your application handles the traffic you actually expect, not just the traffic your laptop can produce.
This guide covers what load testing means for PHP, how to pick the right tool, how the main options compare, and how to write and run a real multi-step load test — on plain PHP or Laravel — in minutes.
PHP load testing verifies your application handles real traffic levels — not just your laptop's dev server. VoltTest lets you write load tests in PHP, install via Composer, and scale from local runs to 10M+ concurrent users in the cloud. This guide covers tool selection, comparison, and step-by-step implementation for both plain PHP and Laravel.
