PHP Developer Day to Day: What Does the Role Involve?

PHP developer day to day work remains one of the most common roles in web development, and it's worth understanding what it actually involves before hiring for it. Here's a concrete look at the split between building new features and maintaining applications already in production.

Building new features

A significant part of a PHP developer's work involves designing and building features for websites or web applications: forms, admin back-offices, third-party integrations, and APIs that connect to other systems. This work generally follows a cycle of design, development, testing, and deployment, often repeated many times over a project's life.

Maintaining and evolving existing applications

A large share of PHP work also involves maintaining applications already in production: fixing bugs, updating dependencies, improving security, and optimizing performance as usage grows. This work requires a strong ability to quickly understand existing code, which is sometimes poorly documented or written by someone no longer available to ask.

Cross-cutting daily tasks

• Working with designers to faithfully integrate mockups into working interfaces
• Talking with product or business teams to clarify functional requirements before building
• Writing automated tests to protect future changes from introducing regressions
• Keeping up with developments in the PHP language and its surrounding ecosystem

How the role shifts with seniority

A junior PHP developer typically works on well-scoped tickets under supervision, while a senior developer takes ownership of architecture decisions and often reviews the work of others. Understanding where a candidate sits on this spectrum helps set realistic expectations for a mission.

A role that demands rigor

Beyond the technical side, a good PHP developer needs to be able to document their work and communicate clearly with non-technical stakeholders. To learn more about this role, read our complete guide to PHP, browse the PHP blog section, and check the PHP projects published on the platform.
