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 build 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 server-side scripting language used heavily in web development, including templates, frameworks, and content management systems. That code is often embedded directly in a page’s HTML, which is why so many pages on the web carry the .php extension. Modern versions, now on PHP 8, are fast, mature, and more capable than ever, and our developers use it to build the dynamic sites your business runs on.
This page explains what PHP developers do, the work our developers deliver, the skills that separate strong PHP developers from the rest, and why TESSA is the right team for your project. Want reliable custom software built right the first time? Call 1-800-586-1553 or Book a Free Strategy Call
What Is a PHP Developer?
A PHP developer is a software developer who specializes in PHP, the server-side language that powers dynamic websites and web applications. PHP developers write the code that runs on the web server, 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 websites and build the engine behind them, while front-end code handles what users see.
Most PHP developers work across the stack. A capable PHP web developer writes PHP scripts on the server, connects to databases, builds and consumes an application program 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 as a full stack developer from the database to the browser. Our PHP developers bring exactly that range to every project.
Write Server-Side Code
PHP developers write the code that runs on the web server. They build PHP scripts that handle requests, process user input and user requests, talk to databases, and generate the content your website serves to each user and visitor.
Build Web Applications
PHP developers build full applications, not just pages. From customer portals to internal tools, PHP developers create the apps and php applications that run your business logic securely on the server.
Work With Frameworks
Strong PHP developers use a PHP framework to build faster and safer. Whether it is Laravel, Symfony, the Zend framework, or vanilla PHP, our PHP developers pick the right tool, drawing on various PHP frameworks for each project.
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 on the web server.
Handle Security
Good PHP developers build security in. They validate user input, manage user authentication, prevent common security vulnerabilities, guard against malicious code, and implement user authentication so your software and each user’ 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.

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. Choosing this language for your project means building on one of the most proven, widely supported languages in programming in the world, a language with staying power, with a deep talent pool of PHP developers and a mature ecosystem of frameworks and tools.
The language has also evolved dramatically. Today, on PHP 8, runs far faster than older PHP versions, with strict typing, modern syntax, and performance that rivals other server-side languages. For most business websites and apps, it remains one of the most cost-effective, reliable choices available, which is exactly why our team continues to build on it for clients every day.
Proven and Everywhere
It 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 runtime in PHP 8 interprets and executes code far faster than older PHP versions, so the dynamic sites our PHP developers build feel responsive and handle real traffic with ease.
Cost-Effective
It is open source and widely supported, which keeps costs down. Hosting is inexpensive, the talent pool is deep, and proven frameworks accelerate development, so your project delivers 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 our PHP developers 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. Our PHP developers choose among various PHP frameworks to match 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 project sustainable: your software 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 PHP developers combine deep technical skills with the judgment to build 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 our PHP developers bring to every engagement.
Core PHP Mastery
Strong PHP developers know the language deeply. They write code and clean PHP scripts, understand script execution and the PHP runtime, and work comfortably in both plain PHP and a modern PHP framework, choosing the right approach for each task.
Full-Stack Range
The best PHP developer is often a full stack developer. A full stack PHP developer handles server-side 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, our PHP developers use various PHP frameworks and modern tooling, drawing on the right framework to build faster without sacrificing quality.
Security Awareness
Great PHP developers build secure software. They validate user input, prevent security vulnerabilities, block malicious code, and implement user authentication correctly, because on the web 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; every software engineer 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 the next feature, not just the next feature. That blend of technical skill and product judgment is what you get from TESSA’s PHP developers, and it is what turns code into software that genuinely serves your business.
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 web developer also reaches for the languages a modern web developer needs that shape the browser experience and the tools that tie a project together. Here is the toolkit our PHP developers and software engineers bring; every software engineer involved raises the bar.
PHP and Server-Side Languages
It is the core, but our developers know how it fits among other programming languages. A senior software engineer can compare PHP with other languages like Java or Python, and a developer who knows Java brings useful perspective even on a PHP project, since Java and PHP solve similar server-side problems and recommend the right choice, though among all these languages, for most web work it 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 CSS for structure and style and JavaScript for interactivity, so the pages PHP generates look and behave exactly as intended. Strong HTML CSS JavaScript skills, real HTML CSS JavaScript fluency, are non-negotiable for any real web developer, and every web developer on our team has them.
JavaScript Front Ends
Modern front ends lean heavily on JavaScript. Our developers pair PHP back ends with JavaScript front ends, so a skilled PHP web developer can deliver a rich, interactive experience while keeping the server-side logic clean and secure.
Databases and APIs
Behind the languages sit databases and APIs. Our PHP developers design databases, write efficient queries, and build the API layers that let your software talk to other platforms across different operating systems.
Frameworks and Platforms
From a PHP framework like Laravel to the platform your business already runs on, our developers work where your project lives, on whatever platform fits. A full stack developer on our team works full stack, moving easily between the server, the database, and the front end on a single platform.
The Broader Ecosystem
Good software engineers keep learning. Our PHP developers stay current with new tools, programming patterns, and tools, so your project benefits from modern programming practice rather than the way programming was done a decade ago.
This breadth is what makes a PHP developer valuable. A web developer who only knows the language can write the server-side code, but a true full stack developer, fluent in server-side code, HTML CSS, JavaScript, and the surrounding languages, can deliver the entire product. As a web developer and software engineer, and as a versatile software engineer, each member of our team brings that full range, so your project is never limited by one narrow skill set. Whether you need a PHP web developer for a focused task or a full stack developer for a complete build, our developers have the languages, the frameworks, and the experience to deliver. Each one is a working web developer and software engineer who knows the major programming languages and works across several languages, and as a software developer with command of modern programming, every one of them brings real range.
Full-Stack PHP Capability
Most real projects need more than server-side code. They need a full stack developer who can handle the full stack: the database, the server-side code on the web server, and the front end the user actually touches. Our PHP developers work as full stack developers, and a good full stack developer covers the entire application so you do not have to coordinate separate specialists who never talk to each other.
This full stack capability matters. A full stack developer can take a project from an empty repository to a launched product, as a full stack developer handling new builds end to end. When you hire TESSA, your full stack team, your full stack developers, your server-side talent, and your front-end specialists all sit on one team, so the server-side code and the browser-side code fit together seamlessly.
Back-End PHP
On the server, our PHP developers write the scripts, build the APIs, and design the databases that power your application. This is the core of full stack work: reliable, secure, fast server-side code that handles your business logic.
Front-End Integration
A full stack developer also handles the front end. Our PHP developers build interfaces with HTML, CSS, 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 full stack developers deliver complete products. One team owns the database, the server-side code, 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, and because they are in such high demand, vetting a candidate’s experience takes time, and one developer rarely covers every skill your project 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 your project requires.
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 your project 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 your project 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 your project 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, choosing the right foundation for each project rather than forcing every job through the same tool. Whether your project calls for a full framework, a content management system, or carefully written plain PHP, our PHP developers have the experience to deliver.
Laravel and Symfony
For custom software, modern frameworks like Laravel and Symfony accelerate development while keeping code clean. Our PHP developers use these frameworks to build 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. Our PHP developers bring experience with the Zend framework and its modern successor, building 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 platform language 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 platforms or any PHP platform, our PHP developers 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, our PHP developers write clean vanilla PHP, avoiding unnecessary complexity while keeping the code readable and easy to maintain.
Headless and APIs
It works beautifully as a back end for modern front ends. Our PHP developers build PHP-powered APIs that feed JavaScript front ends and mobile apps, so your software stays flexible across platforms and devices.
This range is what lets our PHP developers recommend the right approach rather than the only one they know. For one client a WordPress build is perfect; for another, a custom Laravel application or carefully written vanilla PHP serves better. Our PHP developers assess your business needs first, then choose the framework and platform that fit, so your software is built on the right platform and 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 your project 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 our PHP developers build 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 choose the right PHP framework, design the database, and map the application program interface, so it is built on sound foundations.
Development
Our PHP developers build 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, our PHP developers 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 server-side 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 server-side PHP 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 business sites and apps, PHP remains one of the most proven, cost-effective choices available.
Our PHP developers build 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 build dynamic websites and web applications. The main difference is focus: It 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.
