Kirill Yurovskiy: AI Revolution Comes to PHP

The world of web development is being transformed by artificial intelligence (AI). While AI has already made huge impacts in fields like computer vision, natural language processing, and game playing, its potential to supercharge software development is just starting to be explored. And the revolutionary AI wave is now washing over the PHP ecosystem.

For the millions of developers who use the popular PHP scripting language to build dynamic websites, web apps, and APIs, AI offers the tantalizing prospect of radically accelerating coding workflows through intelligent code generation, error fixing, documentation assistance, and more. The frontier of AI-powered PHP development is unfolding rapidly, with tech giants, startups, and the open source community all releasing innovative tools. Let’s dive into the cutting-edge AI capabilities coming to PHP.

GitHub Copilot Pioneers AI Code Generation

Leading the charge is GitHub Copilot, the famous AI pair programmer trained on a vast corpus of code repositories. Launched in 2021 after being developed by AI research company Anthropic, Copilot quickly became a sensation in the coding world for its ability to generate surprisingly coherent and functional code merely from docstring prompts and inline comments. 

Powered by a large language model in the same transformer-based family as GPT-3, Copilot can understand natural language descriptions and convert them into virtually any programming language, including PHP. Given a prompt like “function to fetch posts from a MySQL database,” Copilot will auto generate the corresponding PHP code using proper syntax, database queries, error handling, and more.

While Copilot doesn’t always produce perfect code, it provides developers with a powerful starting point that can dramatically accelerate coding time. Copilot is also contextually aware, meaning it can analyze the entire file or project to tailor its code generation for stylistic consistency and proper integration with existing code.

The impact of Copilot in the PHP world has already been immense, with many developers reporting massive productivity gains. And with Copilot receiving regular model updates to expand its coding knowledge, its PHP capabilities are rapidly evolving. Read more here.

Tabnine Focuses on Deep Code Understanding

While Copilot rewrote the rules for code generation, another AI player is taking code comprehension to new heights. Tabnine, developed by a team of AI researchers in Israel, uses machine learning not to write full functions but to provide advanced code completions powered by deep coding knowledge.

Traditional code completion tools provide basic syntax autocomplete based on statistical patterns in codebases. But Tabnine aims to actually understand the semantics, logic, and functionality of the code. By training large language models on immense codebases, Tabnine’s AI can grasp coding context and patterns in a profoundly deeper way.

For PHP developers, this means receiving code completion suggestions that aren’t just syntactically valid, but semantically appropriate for the task at hand. Rather than suggesting random method names or language keywords, TabNine’s AI understands the higher-level intent of the code and proffers completions that make sense functionally.

This capability is especially powerful for larger PHP codebases and architectures like WordPress, Laravel, and Symfony, where there are complex frameworks, libraries, and coding patterns to comprehend. Tabnine’s context awareness allows its AI to grasp these higher-level code dynamics and provide functionally-relevant suggestions.

Moreover, Tabnine’s AI can make substantive code transformations, like automatically implementing design patterns, optimizing database queries, or refactoring convoluted logic into cleaner abstractions. With deep coding knowledge guiding the suggestions, Tabnine represents a significant step towards AI tools that truly understand code logic.

Open Source AI Coding Assistants Arise

While Copilot and Tabnine are leading the commercial AI charge, the open source world is also spawning powerful AI-powered coding assistants. One of the most notable is the AI plugin for the popular open source IDE PhpStorm.

Leveraging machine learning models trained on open source codebases, the PhpStorm AI plugin provides intelligent code completion, automated code generation, and on-the-fly error detection and fix suggestions. Its language comprehension capabilities allow it to understand developer intent and provide targeted suggestions based on variables, function context, and data flow.

What’s more, the PhpStorm AI plugin can analyze entire files and projects to detect anti-patterns, security vulnerabilities, performance bottlenecks, and other code issues often overlooked by static analysis tools. By combining deep code understanding with proactive issue scanning, the plugin acts as an ever-vigilant coding assistant.

As an open source tool, the PhpStorm plugin allows developers to inspect and even retrain the AI model on custom codebases. This democratizes AI coding assistance by giving developers full transparency and control over the underlying AI powering their tools.

AI Boosts DevOps and Code Review Tools

Beyond core coding workflows, AI is also enhancing PHP development through augmented DevOps and code review processes. Integrating with popular DevOps tools like GitHub Actions and CI/CD pipelines, AI code scanners can automatically analyze pull requests and commits to detect bugs, anti-patterns, and stylistic issues before they get merged into the main codebase.

AI-powered code review assistants like Kees and Kauna use large language models to pore over proposed code changes, identify problematic areas with human-like reasoning, and provide insightful, natural language review commentary. This fundamentally transforms tedious manual code reviews into highly-leveraged processes accelerated by AI comprehension.

On the DevOps side, AI models can be trained to detect application performance bottlenecks and inefficiencies through static and dynamic code analysis. These AI-powered application performance management (APM) tools can automatically monitor and optimize PHP application performance and resource usage at runtime.

Such AI-driven DevOps capabilities allow PHP teams to embrace AI-augmented software delivery life cycles with built-in intelligent quality control, performance optimization, and actionable data-driven insights at every stage.

The Future of AI-Assisted PHP Development

While the current crop of AI coding tools is already profoundly impacting PHP development workflows, the AI revolution has only just begun. Looking ahead, AI-PHP capabilities will grow even more sophisticated and deeply integrated into the core development experience.

Future AI coding assistants will gain expansive multilingual abilities, understanding and generating code across dozens of programming languages. This will allow for seamless AI assistance spanning the entire modern polyglot application stack, whether it’s PHP on the backend, JavaScript on the frontend, or Python/Java/Go for DevOps and systems code.

AI coding models will also grow more granularly specialized for different coding paradigms, libraries, and application architectures. For example, a model could be custom-trained to deeply understand and provide tailored AI assistance for WordPress theme development, Laravel API development, Symfony framework conventions, and more.

Additionally, AI will grow more adaptive and continuous in its assistance. Rather than developers invoking capabilities through specific tool entry points, the AI coding assistant will always be ambient and contextual. It will learn developers’ personal workflows, coding patterns, and domain knowledge to provide automated, personalized assistance at the exact point of need – fluidly generating, refactoring, explaining, and suggesting code as developers type.

The AI assistant won’t just be augmenting human developers, but enabling new forms of human-AI pair programming and real-time collaborative coding assistance. Developers will gain an omniscient AI pair programmer that intuitively understands their high-level intent, handles low-level logic and implementation details, prevents blindspots and errors, and copilots developers to accelerated, high-quality shipping of AI-augmented software.

As the AI coding revolution progresses, PHP will be at the vanguard of adoption, with its flexibility and broad usage powering web apps and APIs at the beating heart of our digital world. Ultimately, every PHP developer’s experience will be radically transformed by this symbiotic human-AI collaboration that amplifies what developers can understand, create, and achieve through coding.
