PHP Development in Derry

PHP work for Derry organisations, which in practice is often maintaining something built years ago by someone unavailable. The pressing question with inherited PHP is usually the version it runs on: unsupported releases receive no security fixes, and a great deal of business-critical code is sitting on them.

Why this comes up

The problem

A system the business depends on runs on old PHP, the original developer has gone, and every quote to replace it exceeds what the system is nominally worth.

What you get

What we deliver

  • The runtime version established and a path to a supported one
  • The existing code understood and documented before anything is changed
  • Tests added around critical behaviour, so changes can be made with confidence
  • Security review of input handling, which older code routinely gets wrong
  • Incremental modernisation where a rewrite is not justified
  • Modern practice applied to new work — typing, dependency management, version control

PHP Development in Derry — common questions

Is PHP still worth using?
Yes, and the modern language is not what its reputation describes. It is fast, supports proper typing, has excellent tooling and dependency management, and hosting is cheaper and more available than for any alternative. Objections usually concern code written long ago rather than current practice.
What should we do with a legacy system?
Understand it before deciding. Systems dismissed as unmaintainable frequently contain years of accumulated business rules nobody has written down, and a rewrite rediscovers them expensively. Getting to a supported version and adding tests is often better value than replacement.
How serious is an old PHP version?
It is a security matter. Versions past their support window get no fixes for newly discovered vulnerabilities, and hosts eventually force an upgrade at a time of their choosing. Planning the move is considerably cheaper than doing it under a deadline you did not set.
Rewrite or repair?
Repair, unless the system genuinely cannot do what the business now needs. Rewrites take longer than estimated, and during them you maintain two systems while delivering no new value. Incremental modernisation is slower to describe and usually faster to benefit from.
Do you work with businesses across County Londonderry?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Derry businesses do you usually work with?
Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
Do you cover the areas around Derry?
Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
