AI Tools for PHP Development: Current Overview 2024

Artificial Intelligence at the Service of PHP Developers: Overview of Key Tools

The world of PHP development is changing rapidly. In 2024, artificial intelligence has ceased to be just a toy and has turned into a full-fledged programmer's assistant. From code autocompletion to generating entire classes and writing unit tests, AI tools can significantly speed up routine processes. We have prepared an overview of the most notable solutions that every PHP developer should try.

1. GitLab Duo — Built-in AI Assistant

GitLab is actively integrating AI into its CI/CD pipelines. The GitLab Duo tool is available directly in the editor via extensions for VS Code and JetBrains. In the context of PHP, it offers:

• Code Suggestions — predicts the next line, taking into account PHP syntax and popular frameworks (Laravel, Symfony).
• Code Explanation — helps to understand complex parts of legacy projects.
• Merge Request Description Generation — automatically composes documentation for changes.

Pros: tight integration with GitLab, security (code does not leave the company's infrastructure). Cons: requires a paid Ultimate subscription.

2. Tabnine — Private AI Companion

Tabnine is one of the market veterans. It supports PHP at the level of autocompletion and generation of entire functions. A distinctive feature is that the model can be trained on your codebase, which is especially valuable for closed projects. Key features:

• Completion of lines and entire code blocks (from simple loops to complex SQL queries via PDO).
• Generation of PHPDoc comments and type annotations.
• Context-aware refactoring (e.g., converting procedural code to OOP).

Tabnine works locally (up to 90% of requests are processed on the device), which is ideal for working with sensitive data.

3. Codeium (ex-Fireflies) — Free Power

If you are looking for a free alternative to GitHub Copilot, check out Codeium. It offers a generous free tier and excellent PHP support. What it's useful for:

• Fast autocompletion with understanding of PHP 8.x syntax (attributes, named arguments, match expressions).
• Natural language search across the codebase (you can ask: "find the email validation function").
• Test generation (PHPUnit) based on a description in English.

Codeium is especially good for small teams and startups where budget is important.

4. Sourcegraph Cody — Contextual AI for Large Projects

Sourcegraph is known for its code navigation tool. Cody is an AI chat that understands your entire codebase. For a PHP developer, this means:

• Answers to questions like "how is this service used in other controllers?".
• Automatic creation of snippets taking into account existing classes and interfaces.
• Help with migration from outdated PHP versions (e.g., from 5.6 to 8.2).

Cody is great for working with monoliths
