PHP Development
An enormous amount of software that businesses genuinely depend on runs on PHP. Refusing to touch it is a marketing position, not an engineering one — so we work with it, and we say when a rewrite is not worth it.
Working
A running app is an asset
Audit first
Never a rewrite by reflex
Incremental
Modernise module by module
Documented
So you are never stuck again
PHP has an image problem and a deployment reality that contradicts it. A very large share of the business software actually in use — internal tools, order systems, portals, e-commerce back ends — is written in it, works, and is depended on daily. The developer who built it has often moved on, nothing has been updated in years, and every agency approached proposes a rewrite.
That reflex is usually wrong. A rewrite is the highest-risk, highest-cost option available, it delivers no new business value for months, and it discards years of encoded business rules that nobody has written down anywhere else. Our starting position is different: assess first, stabilise, then modernise incrementally where it pays.
We maintain PHP applications, fix their security posture, tune their performance, and build API layers over them so modern front-ends and mobile apps can use the data without the legacy system changing. It is the backbone of our Maintenance & Support work.
The State of Most Inherited PHP
Consistent, predictable, and almost always fixable without starting again.
SQL built by string concatenation
User input interpolated straight into queries. It is the oldest vulnerability there is, it is still the most common thing we find, and it is usually fixable file by file without touching anything else.
Running on an end-of-life PHP version
A version that stopped receiving security patches years ago, kept because nobody was sure what would break. The upgrade is normally far smaller than feared once the actual incompatibilities are listed.
Credentials committed to the repository
Database passwords, API keys and SMTP credentials sitting in config files in source control. Exposed to everyone who has ever had a copy of the code, including former staff.
No deployment process at all
Changes made by editing files on the live server over FTP. No version control on what is actually running, no way back, and no environment to test in before customers see it.
PHP Capabilities
Stabilise what exists, secure it, and modernise only where the return justifies it.
Codebase & Security Audit
Static analysis, dependency vulnerability scanning and a manual review of authentication, input handling and query construction — delivered as a written summary with priorities.
Security Remediation
Parameterised queries, output escaping, session and authentication hardening, secrets moved out of source control, and dependency updates against known advisories.
Performance Optimisation
Query profiling, index work, caching and fixing the N+1 patterns that make a page slow — with measured before-and-after timings rather than an assurance.
Version Upgrades
Moving off end-of-life PHP versions incrementally, with the actual incompatibilities enumerated first so the work is a known quantity rather than an open-ended risk.
API Layer Over Legacy
A clean REST API in front of an existing PHP application and its database, so new front-ends, dashboards and mobile apps consume the data without the old system being modified.
Version Control & Deployment
Getting a codebase into Git, establishing a staging environment, and replacing FTP editing with a repeatable deployment that has a way back.
Database Work
MySQL and SQL Server schema review, indexing, migration scripts and reporting queries — frequently where the real performance problem turns out to live.
Framework & Modernisation
Working with Laravel and CodeIgniter codebases, and restructuring unframeworked applications incrementally so each step is independently useful.
Documentation & Handover
Architecture notes, environment setup and a deployment runbook, so the knowledge lives in the repository rather than in one person's memory.
Working With Software Somebody Else Wrote
Assess before proposing anything
The rewrite reflex is commercially convenient for a development agency and rarely right for the client. It is the largest possible engagement, it delivers no new business value for months, and it silently discards years of accumulated business rules — the edge cases, the exceptions, the special handling for one important customer — that exist nowhere except in that code.
So we start with an assessment: static analysis for an objective baseline, dependency vulnerability scanning, and a manual review of authentication, input handling, query construction and deployment. You get a written summary separating what is genuinely urgent from what merely looks dated. Frequently the honest answer is that the application is fine and needs three specific fixes, which is a smaller project for us and the correct advice.
- Written assessment before any proposal
- Urgent security issues separated from cosmetic concerns
- Business rules in the existing code treated as an asset
- We will say when a rewrite is not justified
Security first, because the risk is asymmetric
In an unmaintained PHP application the most likely serious event is not a performance problem, it is a breach. SQL injection through concatenated queries, an end-of-life runtime with published vulnerabilities, credentials in source control, sessions that never expire — any one of these is enough, and the consequences fall on the business rather than on the developer who left.
That work is also usually contained. Parameterised queries can be applied file by file, secrets moved to environment configuration in an afternoon, dependencies updated against advisories, authentication and session handling hardened without touching business logic. It is unglamorous, it does not produce a demo, and it is almost always the highest-value work available in an inherited codebase.
- Parameterised queries applied incrementally, file by file
- Secrets moved out of source control into environment configuration
- Dependencies scanned and patched against published advisories
- Authentication, session and access control hardened
Build alongside rather than through
When a client needs a modern dashboard, a mobile app or a new module and the data lives in an older PHP application, changing that application is rarely the right first move. Adding to a codebase nobody fully understands, with no tests and no staging environment, is how a small feature becomes an incident.
We put a clean REST API in front of the existing database instead, with explicit read and write boundaries. New front-ends — Angular, Next.js or a Flutter app — consume that API without the legacy system being modified at all. Value arrives in weeks rather than after a rewrite, and once the new layer carries real traffic you have a realistic basis for deciding whether replacing the old system is worth it.
- API layer over the existing database, legacy code untouched
- Clear read and write boundaries so integrity is preserved
- Modern front-ends and mobile apps served without a rewrite
- A real basis for the eventual replace-or-keep decision
When we would not choose PHP
We maintain PHP because businesses depend on it. For new work our default is different, and we will say so plainly:
- Building something new? We would use Django. Transactions, migrations, permissions and admin are solved for you, which matters most on business systems.
- Heavy data or AI work? Python's ecosystem is not close to matched. Do not fight that.
- Real-time features? Persistent connections and streaming are a poor fit for PHP's request model. Use a runtime built for it.
- Sometimes the rewrite IS right. No source control, no tests, an unsupported runtime and a schema that cannot support what the business now needs — at that point rebuilding is genuinely cheaper. We will tell you when you are in that case.

Frequently Asked Questions
Yes — it is a large part of our maintenance work. A running application that a business depends on is an asset, not a problem to be replaced on principle. We start with a written assessment covering security, dependencies, performance and deployment, and separate what is genuinely urgent from what merely looks dated.
