PhpStorm 2025.3 brings bundled Laravel support, PHP 8.5, and new AI agents

PhpStorm 2025.3 is out, and this release comes with native Claude Agent integration, out-of-the-box Laravel support, support for PHP 8.5, improvements in generics, a new Islands theme, and more.

With this release, Laravel developers now get first class framework support without installing extra plugins or paying for add ons because they brought the Laravel Idea plugin into the core of the product.

PHP 8.5 is now fully supported with full editor support and inspections, and JetBrains is leaning harder into AI inside the IDE, including native Claude Agent integration and better control over costs.

Laravel Support

PhpStorm 2025.3 turns Laravel support into a built in feature.

The Laravel Idea plugin is now bundled, so new and existing projects get route, view, config, translation, and Blade navigation without any setup.
Developers keep all the quality of life helpers from Laravel Idea, including container and facade aware completion, Eloquent model helpers, and artisan integrations.
JetBrains says Laravel Idea creator Adel Faizrakhmanov will continue shipping new Laravel features that are now delivered as part of PhpStorm itself.
Pest support for all the new features introduced in Pest v4, including Playwright-powered browser testing.

PHP 8.5

PhpStorm 2025.3 has support for PHP 8.5, and you can try new features by setting the project language level to PHP 8.5. Some highlights include:

Cloning objects with properties
Closures in constant expressions
Pipe operator |>
#[NoDiscard] attribute
Final property promotion, where a __constructor parameter marked with final is considered promoted and treated like other promoted properties.
Asymmetric visibility for static properties, similar to asymmetric visibility for object properties, which was implemented in PHP 8.4.
The array_first() and array_last() functions, which return the first and last values of an array.
Attributes for constants that are allowed to target the constants declared in their own statements.
Generics improvements

JetBrains AI

Multi-agent experience: Junie and Claude Agent - Claude Agent has become the first third-party AI agent natively integrated into JetBrains IDEs. With its addition, JetBrains introduces a multi-agent experience that brings even more flexibility and power to your development workflow. Now that Claude Agent and Junie are available in the same chat interface, you can switch between agents seamlessly and get the right kind of assistance for every task.
Transparent AI quota tracking in the IDE - You can now view your remaining AI credits, renewal date, and top-up balance directly inside your IDE, and if you run out of credits, you can initiate a top-up from there as well.
Streamlined MCP server setup - They improved the way MCP server configurations are imported from other tools. When you first open a project with anmcp.json file in it, PhpStorm will automatically fetch the configured MCP servers and prompt you to view or enable them in the IDE settings.
Bring Your Own Key (coming soon) - BYOK will let you connect your own API keys from OpenAI, Anthropic, or any OpenAI API-compatible local model, giving you more flexibility and control over how you use AI in JetBrains IDEs. You’ll be able to use your favorite AI chat and agents without logging into JetBrains AI, which is perfect for developers who already have API keys and want to work with their preferred provider.

New Islands theme

The Islands theme is now the default look in PhpStorm. More than just a visual refresh, it reflects their commitment to providing the ultimate comfort throughout your development experience.

Instantly recognizable tabs, improved in-editor contrast, clear separation between working areas, and rounded corners create a soft and balanced environment that was designed around one goal: helping you stay focused and code with ease.
