Keeping a Symfony 1 / PHP 5.4 website safely in business

A property website on Symfony 1 and PHP 5.4 still earned its keep. We maintain it carefully — SEO updates, feeds, cache issues — and brought production changes back under Git control.

PHP 5.4 stack kept safely serving the business
Git restored as the source of truth for production

A property listings business runs on a website built with Symfony 1 and PHP 5.4 — a stack most agencies refuse to touch. The site still supports real business activity, so “just rebuild it” was exactly the wrong answer.

The challenge

  • Fragile production behaviour, where small changes could carry real risk.
  • Years of direct FTP and server edits had let production drift away from version control.
  • Cache problems meant old content sometimes kept appearing after updates.
  • The business still needed ongoing SEO, content and property-feed updates.

What we did

  • Made careful, tested changes inside the existing codebase, respecting the limits of the old stack.
  • Traced the cache and content-mismatch issues to their root cause instead of applying surface edits.
  • Kept the property feeds and SEO/content updates flowing so the site stayed commercially useful.
  • Reconstructed what actually runs in production and brought it back into Git — restoring version control as the source of truth.

The outcome

The site keeps doing its job on a fourteen-year-old stack, changes are predictable instead of frightening, and production is back under version control. When the business decides to modernise, it can do so from a stable position — not from a crisis.

We regularly rebuild the picture from whatever exists — even when the only copy of the code lives on the production server. That is the core of our application takeover and legacy PHP work.
