Still Relying on Composer Autoload? Runtime Module Injection Is the Future

Hold up. Are we still talking about autoloaders like it’s 2010?

If you’re firing up every PHP request with Composer’s autoload dragging a forest of require trees behind it, you're not alone—but you're also not future-proof.

PHP devs have been clinging to autoload.php like a comfort blanket, even when modern runtime logic is screaming for more agility, more context-awareness, and less static baggage.

And now, with the rise of dynamic module loading, the game’s shifting—fast.

Why Composer Autoload Is Starting to Suck?

Composer’s autoload was a damn good innovation for its time. But in a world where we're microservicing everything, pushing event-driven boundaries, and flirting with serverless architecture, static wiring is a bottleneck in disguise.

It loads classes upfront. Period. Doesn’t care if you’re just running a CLI command or serving a lightweight endpoint.

Doesn’t know if half your dependencies won’t even be touched. It bloats memory, clutters boot times, and hardcodes too many assumptions.
