PHP powers 77% of all websites with a known server-side language. WordPress alone runs 43% of the web. Yet PHP developers are often an afterthought for AI coding tools built with JavaScript and Python in mind.
We tested every major AI coding assistant on PHP-specific tasks — WordPress plugin development, Laravel and Symfony patterns, legacy code modernization, Composer dependency management, PHPUnit testing, and PhpStorm compatibility — to find which one actually helps PHP developers the most.
Best overall for PHP: GitHub Copilot Pro ($10/mo) — widest PhpStorm support, strong Laravel/WordPress completions, enterprise-ready. Best free: Amazon Q Developer — unlimited completions, works in PhpStorm, good for general PHP. Best for legacy migration: Claude Code — terminal agent that handles PHP 5.x to 8.x upgrades across entire codebases. Best IDE experience: Cursor Pro ($20/mo) — strongest codebase-aware completions for Laravel/Symfony projects.
Why PHP Is Different
PHP occupies a unique position in the programming world that creates distinct challenges for AI coding tools:
- Legacy is the norm, not the exception — most PHP codebases aren't greenfield Laravel apps. They're WordPress plugins, Drupal modules, or custom applications written in PHP 5.x that need modernization. AI tools need to understand both old and new PHP.
- WordPress is its own ecosystem — hooks, filters, actions, the Settings API, WP_Query, custom post types, Gutenberg blocks. WordPress PHP isn't "normal" PHP. An AI that generates Laravel-style code in a WordPress context is actively harmful.
- Mixed HTML/PHP templates — Blade (Laravel), Twig (Symfony), or raw PHP templates mixing
<?phptags with HTML. AI tools need to handle context switching between languages mid-file. - PhpStorm dominance — professional PHP developers overwhelmingly use PhpStorm (JetBrains). Tools that only work in VS Code miss most of the market.
- Massive version gap — PHP 5.6 to PHP 8.3 is a huge leap (typed properties, enums, fibers, match expressions, named arguments, union/intersection types). AI tools that default to old PHP patterns waste your time.
The Legacy Code Challenge
No other language has PHP's legacy problem at scale. There are millions of WordPress plugins, thousands of enterprise apps, and countless custom CMSes still running PHP 7.x or even 5.6. The AI tool that helps you modernize this code — not just write new code — delivers the most real-world value.
We tested each tool on a representative legacy migration task: upgrading a PHP 7.2 WordPress plugin to PHP 8.1+ with typed properties, enums, match expressions, and named arguments while preserving WordPress coding standards. Here's how they performed:
| Tool | Legacy Migration | Notes |
|---|---|---|
| Claude Code | Excellent | Handles full-codebase migration, runs PHPUnit, iterates on failures |
| Cursor | Good | Composer handles multi-file upgrades well within open project |
| Copilot | Decent | Good at per-file suggestions, limited cross-file awareness |
| Gemini | Basic | Understands new syntax, but won't proactively modernize |
| Amazon Q | Basic | No PHP-specific migration tooling (Java only) |
PHP Feature Comparison
| Feature | Copilot | Cursor | Claude Code | Windsurf | Gemini | Amazon Q |
|---|---|---|---|---|---|---|
| WordPress (hooks, WP_Query) | Strong | Strong | Excellent | Good | Good | Basic |
| Laravel (Eloquent, Blade) | Strong | Excellent | Strong | Good | Good | Basic |
| Symfony (Doctrine, Twig) | Good | Strong | Strong | Good | Good | Basic |
| PHP 8.x features | Strong | Strong | Excellent | Good | Good | Good |
| PHPUnit / Pest | Strong | Strong | Excellent | Good | Good | Good |
| Composer / Packagist | Good | Good | Excellent | Good | Basic | Basic |
| Mixed HTML/PHP | Strong | Strong | Good | Good | Good | Good |

Tool-by-Tool Breakdown for PHP
GitHub Copilot — The Safe Choice for PhpStorm
Copilot has the deepest PhpStorm integration of any AI coding tool. For PHP developers who live in JetBrains, it's the path of least resistance with consistently good results.
PHP strengths:
- Excellent inline completions for WordPress hooks, actions, and filters — correctly suggests
add_action(),apply_filters(), sanitization functions - Strong Laravel Eloquent and Blade template completions — understands relationships, scopes, middleware
- Good at generating PHPDoc blocks and type hints for PHP 8.x code
- Works natively in PhpStorm via official JetBrains plugin — no workarounds needed
- Agent mode (Copilot Workspace) can scaffold Laravel CRUD operations end-to-end
PHP weaknesses:
- Free tier (2,000 completions/month) runs out fast in verbose PHP codebases
- Sometimes generates PHP 7.x patterns when 8.x syntax would be better — doesn't proactively modernize
- WordPress Gutenberg block development (React JSX inside a PHP plugin) confuses the context sometimes
Best for: PHP developers using PhpStorm who want reliable AI without disrupting their workflow. Strongest all-around option for mixed WordPress/Laravel work.

Cursor — Best IDE for Modern PHP (Laravel/Symfony)
Cursor's codebase-wide context awareness is a game-changer for large Laravel and Symfony projects where models, controllers, services, and templates all reference each other across dozens of files.
PHP strengths:
- Codebase-aware completions understand your Eloquent models when you're writing controllers in a different file
- Composer (agent mode) can scaffold entire Laravel features — model, migration, controller, test, route — in one pass
- Best Blade/Twig template completions of any tool — correctly resolves variables passed from controllers
- Strong PHP 8.x awareness — defaults to modern syntax (enums, match, named arguments) when your project uses them
- Tab completion handles mixed HTML/PHP context well
PHP weaknesses:
- VS Code fork — PhpStorm users must switch editors or use ACP (IntelliJ 2026.1+)
- WordPress-specific patterns (hooks, Settings API, custom post types) are less polished than Copilot's
- 500 fast requests at $20/mo — heavy agent usage for big refactors can exhaust this
Best for: Laravel and Symfony developers open to using VS Code. The codebase-aware completions are genuinely better than any other tool for large PHP projects.

Claude Code — Best for Legacy PHP Migration
Claude Code is the only tool that can realistically handle a full PHP version migration. It reads your entire codebase, identifies PHP 5.x/7.x patterns, generates the modern equivalent, runs PHPUnit, and iterates until tests pass. No other tool does this autonomously.
PHP strengths:
- Handles full-codebase PHP version upgrades — 5.6 to 7.4, 7.x to 8.1+ — correctly replacing deprecated functions, adding type declarations, converting to named arguments
- Deep WordPress knowledge — generates plugins that follow WordPress coding standards, uses proper sanitization/escaping, understands the plugin lifecycle
- Runs PHPUnit and Pest tests directly, iterates on failures until they pass
- Manages Composer dependencies — adds packages, resolves conflicts, updates autoload
- Works alongside PhpStorm (terminal-based) — no IDE switching required
- Excellent at explaining legacy PHP code — reads spaghetti code and produces clear explanations
PHP weaknesses:
- No autocomplete. This is an agent you talk to, not a copilot that suggests as you type.
- Starts at $20/mo (Claude Max). Heavy migration projects may need $100/mo (Max 5x) or $200/mo (Max 20x).
- Not ideal for quick inline completions during normal coding — pair it with Copilot or Cursor for daily work.
Best for: PHP developers facing version migrations, large refactors, or inheriting legacy codebases. The single best tool for turning PHP 5.x spaghetti into modern PHP 8.x code.

Windsurf — Capable But Less PHP-Specific
Windsurf (formerly Codeium) offers a solid general PHP experience with its Cascade agent mode. It handles standard PHP patterns well but doesn't have the PHP-specific depth of Copilot or Cursor.
PHP strengths:
- Cascade agent handles multi-file PHP edits competently
- Good completions for standard PHP patterns and PSR standards
- Free tier is generous for casual use
- JetBrains plugin available for PhpStorm
PHP weaknesses:
- Quota system means you might hit limits mid-session — unpredictable for heavy coding days
- WordPress-specific knowledge is shallow — often generates generic PHP instead of WP patterns
- Laravel/Symfony framework understanding is behind Cursor and Copilot

Gemini Code Assist — Massive Free Tier, Basic PHP
Gemini Code Assist offers 180,000 free completions per month — more than enough for any PHP developer. But its PHP-specific knowledge, especially around WordPress and Laravel, lags behind Copilot and Cursor.
PHP strengths:
- 180,000 free completions/month — most PHP developers will never need a paid plan
- Decent modern PHP (8.x) suggestions — understands typed properties, enums, match
- Works in VS Code and JetBrains via plugin
- 1M token context window useful for understanding large PHP codebases
PHP weaknesses:
- WordPress hook/filter knowledge is shallow — often generates incorrect action/filter names
- Laravel Eloquent completions are less accurate than Copilot or Cursor — misses scopes, relationships
- Agent mode less mature than competitors for PHP-specific tasks
Full Gemini pricing breakdown →
Amazon Q Developer — Best Free Option
Amazon Q offers unlimited free completions and works in PhpStorm. For PHP developers on a budget, especially those deploying to AWS, it's a strong no-cost option.
PHP strengths:
- Unlimited free completions — no monthly limits whatsoever
- Works in PhpStorm via official JetBrains plugin
- Security scanning catches common PHP vulnerabilities (SQL injection, XSS, CSRF)
- Good for AWS-hosted PHP (Lambda with PHP runtime, Elastic Beanstalk patterns)
PHP weaknesses:
- General PHP completion quality lags behind Copilot and Cursor
- WordPress and Laravel knowledge is minimal — treats PHP as a generic language
- No PHP-specific migration or upgrade tooling (unlike its Java upgrade feature)
Full Amazon Q pricing breakdown →
JetBrains AI — For PhpStorm Loyalists
If PhpStorm is non-negotiable and you already have a JetBrains subscription, their built-in AI assistant leverages PhpStorm's deep PHP understanding in ways external plugins can't match.
PHP strengths:
- Leverages PhpStorm's existing PHP intelligence — type inference, namespace resolution, Composer autoload awareness
- AI-powered inspections that understand PHP-specific anti-patterns (e.g.,
mysql_*function usage, missing prepared statements) - Integrated into PhpStorm's refactoring tools — rename, extract method, change signature with AI suggestions
- Understands your project's PHP version and suggests appropriate syntax
PHP weaknesses:
- Included with PhpStorm subscription (~$25/mo or $8.33/mo bundled) — not free
- AI model quality behind Copilot and Cursor (uses various models including Gemini)
- Framework-specific AI features (WordPress, Laravel) are less developed than the general PHP intelligence

Tabnine — Privacy-First PHP
For PHP teams in regulated industries (healthcare, government, finance), Tabnine's code-never-leaves-your-network promise is a differentiator. Enterprise tier offers on-premise deployment.
PHP strengths:
- Code never used for training, on-premise option available
- Decent PHP completions at the lowest price ($9/mo)
- Works in PhpStorm and all JetBrains IDEs
PHP weaknesses:
- PHP completion quality notably behind Copilot and Cursor
- WordPress/Laravel framework knowledge is minimal
- No agent capabilities for multi-file PHP refactoring

The PhpStorm Question
Like Java developers and IntelliJ, PHP developers face a tool compatibility question that limits their options. Most professional PHP developers use PhpStorm, and this matters more than raw AI quality.
If you use PhpStorm, your best options are:
- Copilot (Free–$39/mo) — best overall quality in PhpStorm, strongest WordPress/Laravel support
- JetBrains AI (bundled with subscription) — deepest PhpStorm integration, leverages built-in PHP intelligence
- Amazon Q (Free–$19/mo) — unlimited free, JetBrains plugin
- Gemini Code Assist (Free–$19.99/mo) — massive free tier, JetBrains plugin
- Tabnine ($9–$39/mo) — privacy-first, JetBrains plugin
- Claude Code ($20–$200/mo) — terminal-based, works alongside PhpStorm
- Cursor (Free–$200/mo) — via ACP in IntelliJ 2026.1+ (PhpStorm 2026.1+)
If you're open to VS Code, Cursor gives the best PHP IDE experience for modern framework development. But Copilot in PhpStorm is genuinely good and improving rapidly.
WordPress-Specific Recommendations
WordPress development is different enough from general PHP to warrant its own section. The ideal tool needs to know:
- The hooks system —
add_action(),add_filter(),do_action(),apply_filters()with correct hook names - WordPress coding standards — WPCS uses specific formatting, naming conventions (
snake_casefunctions,$prefix_globals) - Security functions —
wp_nonce_field(),sanitize_text_field(),esc_html(),$wpdb->prepare() - WP-CLI commands and plugin scaffolding
- Gutenberg blocks — React JSX in a PHP plugin context
For WordPress: Copilot Pro ($10/mo) is the clear winner. It has the deepest training on WordPress code (GitHub hosts millions of WP plugins/themes), works in PhpStorm, and its completions correctly use WordPress-specific sanitization and escaping functions. Claude Code is the runner-up for complex plugin architecture and migration work.
Our Verdict
For most PHP developers, Copilot Pro offers the best combination of WordPress/Laravel knowledge, PhpStorm compatibility, and consistent quality. The 300 premium requests/month covers typical daily usage, and it works everywhere PHP developers already work.
Unlimited completions, PhpStorm plugin, and decent general PHP quality. The WordPress and Laravel knowledge is basic, but for standard PHP work and budget-conscious developers, it's hard to beat free-with-no-limits.
If you're facing a PHP version upgrade, inheriting a legacy codebase, or need to modernize old WordPress plugins, Claude Code is the only tool that can realistically handle full-codebase migrations. Pair it with Copilot for daily completions.
Use Amazon Q's unlimited completions for volume work. Add Copilot Pro for premium requests with stronger WordPress/Laravel knowledge. Total cost: $10/month for a setup that covers the full spectrum of PHP development.
