PHP Developers Who Build Custom Websites That Work
PHP powers a huge share of the web. From popular platforms to custom platforms, PHP is the server-side language behind millions of websites, and skilled PHP developers are the people who put it to work for your business. At TESSA Marketing & Technology, our PHP developers create custom websites, web applications, and content management systems for businesses around Washington DC and across the country. When you need developers who write clean, reliable code and ship software that genuinely works, TESSA is the partner to call.
PHP stands for Hypertext Preprocessor. It is a scripting language that runs on the server and is used heavily in web development, including templates, frameworks, and CMS platforms. That code is often embedded directly in a page’s HTML, which is why so many pages carry the .php extension. Modern versions, now on PHP 8, are fast, mature, and more capable than ever, and our developers use it to create the dynamic sites your business runs on.
This page explains what PHP developers do, the work we deliver, the skills that separate the strong ones from the rest, and why TESSA is the right team for your project. Want reliable custom software built right the first time? Call 703-214-9555 or Book a Free Strategy Call
What Is a PHP Developer?
A PHP developer is a software developer who specializes in PHP, the language that runs on the server and powers dynamic websites and web applications. PHP developers write the code that runs there, handling the programming a static page cannot: user accounts, user sessions, databases, forms, payments, and content that changes for each visitor. In short, PHP developers create the engine behind a website, while front-end code handles what users see.
Most PHP developers work across the stack. A capable one writes scripts on the server, connects to databases, builds and consumes an application programming interface, and often handles front end development with HTML, CSS, and JavaScript too. That breadth is why a strong PHP developer is frequently described as a full stack developer, comfortable working from the database to the browser. Ours bring exactly that range to every engagement.
Write Server-Side Code
PHP developers write the code that runs on the web server. They write the scripts that handle requests, process user input, talk to databases, and generate the content your website serves to each visitor.
Build Web Applications
PHP developers deliver full applications, not just pages. From customer portals to internal tools, they create the apps and PHP applications that run your business logic securely on the server.
Work With Frameworks
Strong PHP developers use a framework to ship faster and safer. Whether it is Laravel, Symfony, the Zend framework, or vanilla PHP, ours pick the right tool from the PHP frameworks available for the job.
Manage Databases
PHP developers connect your application to its data. They design database structures, write efficient queries, and ensure your dynamic websites read and write data quickly, reliably, and safely.
Handle Security
Good PHP developers design security in. They validate user input, manage user authentication, prevent common vulnerabilities, and guard against malicious code, so your software and each user’s data stay protected.
Maintain and Improve
PHP developers keep software healthy. They ship bug fixes, apply updates across versions, refactor code, and add features over time, so your website keeps performing long after launch.
Great PHP developers are invisible in the best way. Users never see the PHP scripts, the database queries, or the security checks; they just experience a website that is fast, reliable, and always works. That is what skilled PHP developers deliver.

Why PHP Is Still a Smart Choice in 2026
Some people ask whether PHP is still relevant. The answer is a clear yes. PHP powers a majority of the websites on the internet, including the vast WordPress ecosystem, and modern PHP is fast, secure, and actively developed. Picking this language for your project means standing on one of the most proven, widely supported languages in the world, with staying power, a deep talent pool of PHP developers, and a mature ecosystem of frameworks and tools.
The language has also evolved dramatically. Today, PHP 8 runs far faster than older versions, with strict typing, modern syntax, and performance that rivals other back-end languages. For most business websites and apps, it remains one of the most cost-effective, reliable choices available, which is exactly why our team keeps using it for clients every day.
Proven and Everywhere
PHP runs a huge share of the web, from small business websites to major platforms. That ubiquity means proven patterns, deep documentation, and a large community of developers, so your software is built on solid, well-understood ground.
Fast and Modern
Modern versions are quick. The PHP 8 runtime interprets and executes code far faster than its predecessors, so the dynamic sites our PHP developers ship feel responsive and handle real traffic with ease.
Cost-Effective
PHP is open source and widely supported, which keeps costs down. Hosting is inexpensive, the talent pool is deep, and proven frameworks accelerate development, so you get strong value for the investment.
Powers WordPress
WordPress, the most popular CMS platform on earth, is built in PHP. If your site runs on it, you are already running PHP, and we can customize, extend, and secure that site at the code level.
Flexible Frameworks
From Laravel and Symfony to the Zend framework, PHP offers mature frameworks for every kind of project. We match the framework to your needs, balancing speed of development with long-term maintainability.
Easy to Hire For
Because PHP is so widely used, the supply of skilled PHP developers is strong. That keeps your software sustainable: it is written in a language plenty of developers know, so it is never locked to one irreplaceable person.
The Skills of a Great PHP Developer
Not every PHP developer is equal. The best ones combine deep technical skills with the judgment to make the right thing. Whether you are reviewing a candidate’s experience or evaluating a team, these are the technical skills and qualities that separate strong PHP developers from the rest, and they are the skills ours bring to every engagement.
Core PHP Mastery
Strong PHP developers know the language deeply. They write clean scripts, understand script execution and the runtime, and work comfortably in both plain PHP and a modern framework, picking the right approach for each task.
Full-Stack Range
The best PHP developer is often a full stack developer, handling back-end PHP, databases, and front-end coding with HTML, CSS, and JavaScript, so one developer or one team can deliver an entire application.
Frameworks and Tools
Skilled PHP developers know the ecosystem. From Laravel and Symfony to the Zend framework, they use the right framework and modern tooling to move faster without sacrificing quality.
Security Awareness
Great PHP developers write secure software. They validate user input, prevent vulnerabilities, block malicious code, and implement user authentication correctly, because on the server, security is not optional.
Testing and Quality
The best PHP developers write high quality code and test it. Through automated testing and disciplined review, they catch problems early, the habit that separates a professional software engineer from a casual coder. Everyone on our team works this way.
Soft Skills
Technical skills are not everything. The best PHP developers bring strong organizational skills and clear communication, understanding your business needs and explaining trade-offs so your project stays on track and on budget.
When you evaluate PHP developers, look past a checklist of keywords. A strong PHP developer understands your goals, writes maintainable source code, and thinks like a seasoned software engineer about the whole system, because a good software engineer sees more than just the next feature. That blend of technical skill and judgment is what you get from TESSA’s PHP developers, and it is what turns code into software that genuinely serves your goals.
The Languages and Tools Behind PHP Development
A great PHP developer rarely works in PHP alone. Real web development draws on several programming languages and tools, and the best PHP developers are comfortable across many languages and the whole stack. While it runs on the server, a capable developer also reaches for the languages that shape the browser experience and the tools that tie a project together. Here is the toolkit our PHP developers bring.
PHP and Server-Side Languages
PHP is the core, but our developers know how it fits among other programming languages. A senior software engineer can compare PHP with Java or Python, and a developer who knows Java brings useful perspective even on a PHP project, since the two solve similar back-end problems. For most web work, though, PHP remains the natural fit.
HTML, CSS, and JavaScript
Every web developer needs the front-end trio. Our PHP developers write HTML, CSS, and JavaScript fluently, using HTML and CSS for structure and style and JavaScript for interactivity, so the pages PHP generates look and behave exactly as intended. Real fluency in all three is non-negotiable, and everyone on our team has it.
JavaScript Front Ends
Modern front ends lean heavily on JavaScript. Our developers pair PHP back ends with JavaScript interfaces, so a skilled PHP developer can deliver a rich, interactive experience while keeping the server logic clean and secure.
Databases and APIs
Behind the languages sit databases and APIs. Our PHP developers design databases, write efficient queries, and create the API layers that let your software talk to other systems, whatever operating systems and platforms they run on.
Frameworks and Platforms
From a framework like Laravel to the platform you already run on, our developers work where your project lives. Each full stack developer on our team moves easily between the server, the database, and the front end.
The Broader Ecosystem
Good engineers keep learning. Our PHP developers stay current with new tools and programming patterns, so your software benefits from the way code is written now rather than a decade ago.
This breadth is what makes a PHP developer valuable. A developer who only knows the language can write the back-end code, but a true full stack developer, fluent in server-side code, HTML, CSS, JavaScript, and the surrounding languages, can deliver the entire product. Each member of our team is a web developer and software engineer with that full range, so your project is never limited by one narrow skill set. Whether you need a PHP developer for a focused task or a full stack developer for a complete build, our developers have the languages, the tools, and the experience to deliver. Each one is a software engineer who knows the major programming languages and works across several of them, with command of modern programming and real range.
Full-Stack PHP Capability
Most real projects need more than back-end code. They need a full stack developer who can handle the whole thing: the database, the code on the server, and the front end the user actually touches. Our PHP developers work that way, covering the entire application so you do not have to coordinate separate specialists who never talk to each other.
This capability matters. A full stack developer can take a project from an empty repository to a launched product, handling new builds end to end. When you hire TESSA, your full stack developers, your back-end talent, and your front-end specialists all sit on one team, so the server code and the browser code fit together seamlessly.
Back-End PHP
On the server, our PHP developers write the scripts, design the databases, and expose the APIs that power your application. This is the core of full stack work: reliable, secure, fast code that handles your business logic.
Front-End Integration
A full stack developer also handles the front end. Ours craft interfaces with HTML, CSS, and JavaScript, so the data your PHP produces is presented in a clean, responsive interface your customers enjoy using.
End-to-End Delivery
From greenfield projects to ongoing work, our developers deliver complete products. One team owns the database, the back end, and the front end, so nothing falls through the cracks between specialists.
Hire a PHP Team, Not Just One Developer
Many businesses start by trying to hire a single PHP developer. But finding the best candidates is hard: skilled PHP developers are in high demand, so vetting a candidate’s experience takes time, and one developer rarely covers every skill the job needs. When you hire TESSA, you skip all of that. Instead of one hire, you get a complete PHP development team with the full range of skills you require.
Hiring developers one at a time also means managing them, covering gaps when someone is unavailable, and hoping the best candidates stay. With TESSA, the hiring is simple: you bring the project, and our PHP developers, designers, and other developers handle the rest as one accountable team. No vetting a candidate’s experience, no scrambling when a solo developer moves on, and no gap in momentum when a task needs a skill your one hire happens to lack. The team simply brings in whoever is right for that part of the work.
A Full Team
Hiring developers one by one leaves gaps. Our development team pairs PHP developers with a back end developer, front-end specialists, and designers, so every part of the job is covered by someone who does it well.
Proven Expertise
Skip the slow search for the best candidates. Our PHP developers bring deep experience, so you do not have to evaluate each candidate’s experience or worry whether a single developer has the full skill set the job demands.
Accountability
When you hire individual developers, accountability blurs. With TESSA, one development team owns your project end to end, so there is always a clear answer to who is responsible for delivering high quality code on time.
PHP Frameworks and Platforms We Work With
Modern projects rarely start from scratch. Our PHP developers work across the major PHP frameworks and platforms, picking the right foundation for each project rather than forcing every job through the same tool. Whether that means a full framework, a content management system, or carefully written plain PHP, we have the experience to deliver.
Laravel and Symfony
For custom software, modern frameworks like Laravel and Symfony accelerate development while keeping code clean. We use them to ship secure, maintainable software faster than hand-rolling everything from scratch.
The Zend Framework
For enterprise projects, the Zend framework offers a robust, well-structured foundation. We bring experience with the Zend framework and its modern successor, writing software that scales cleanly as your business grows.
WordPress
WordPress runs a huge portion of the web, and it is built in PHP. Our PHP developers work in WordPress at the code level, building custom themes and plugins that go far beyond what off-the-shelf tools allow.
Other PHP Platforms
PHP, the language behind much of the web, powers many content management systems beyond WordPress, including Drupal and Craft CMS. When a project is already built on one of these, or any other PHP platform, we can maintain and extend it with the same care we bring to every codebase.
Vanilla PHP
Sometimes the right answer is no framework at all. For lightweight tools and specific tasks, we write clean vanilla PHP, avoiding unnecessary complexity while keeping the code readable and easy to maintain.
Headless and APIs
PHP works beautifully as a back end for modern front ends. We create PHP-powered APIs that feed JavaScript interfaces and mobile apps, so your software stays flexible across platforms and devices.
This range is what lets us recommend the right approach rather than the only one we know. For one client an off-the-shelf platform is perfect; for another, a custom Laravel application or carefully written vanilla PHP serves better. We assess your needs first, then choose the framework and platform that fit, so your software is built on the right foundation from day one. Too many projects fail because the wrong tool was chosen before anyone understood the goal, locking the business into costly rework later. We start with your goals and let the technical choices follow, which is how a project stays on budget and on schedule.
Our Development Process
Great software comes from a clear process. When you work with TESSA, you always know what is happening and why. Our development process is collaborative and transparent from the first call through launch and beyond, so everything stays on track and the final product reflects your goals.
Discovery and Requirements
We start by understanding your business needs, your users, and your goals. This shapes everything that follows, so we create software that solves the real problem rather than just checking boxes on a brief.
Architecture and Planning
We plan the technical architecture before writing production code. Our developers pick the right PHP framework, design the database, and map the application programming interface, so it is built on sound foundations.
Development
We write your software with clean, tested PHP code. We write maintainable source code, implement user authentication and security, and connect the pieces into a working web application that meets your requirements.
Testing and QA
We test rigorously with automated testing across browsers, devices, and PHP versions. This quality assurance step catches bugs and security vulnerabilities before launch, so your software performs reliably from day one.
Launch and Support
We deploy your software and stay on to support it. As your needs evolve, we ship bug fixes and new features, so your website or application keeps improving long after the initial launch.

Frequently Asked Questions About PHP Developers
What is a PHP developer?
A PHP developer is a software developer who specializes in PHP, the back-end programming language behind a large share of the web. PHP developers write the code that runs on the web server, handling databases, user accounts, forms, and the dynamic content that makes a website more than static pages.
Many PHP developers work as full stack developers, handling both the PHP on the server and the front end. At TESSA, our PHP developers cover the whole stack as one team.
What is a PHP developer’s salary?
PHP developer salaries vary widely by experience and location, and hiring a full-time developer also means benefits, management, and overhead. For many businesses, partnering with an agency is more cost-effective than hiring, because you get a full development team only when you need it.
Rather than a salary, TESSA gives you a clear project quote, so you know exactly what your investment buys before any work begins.
Is PHP still relevant in 2026?
Yes. PHP powers a majority of the websites on the internet, including the entire WordPress ecosystem, and modern PHP 8 is fast, secure, and actively developed. For most sites and apps, PHP remains one of the most proven, cost-effective choices available.
We start new projects on modern PHP every day, and the deep talent pool means your software will be maintainable for years to come.
Is PHP like Python?
PHP and Python are both popular server-side languages, and both can power dynamic websites and web applications. The main difference is focus: PHP was designed specifically for the web and powers most of it, while Python (and Java) is a general-purpose language also popular in data science and automation.
For web projects, especially anything touching WordPress, PHP is often the more natural fit, which is why our software developers reach for it so often.
