# Using Ray with Yii

[Yii](https://www.yiiframework.com/) is a high-performance PHP framework for developing modern web applications. Use Ray to help you debug when you're developing a Yii application, extension or module.

[spatie/yii-ray](https://github.com/spatie/yii-ray)

## [#](/content/docs/php/yii/getting-started#installing-the-package "Permalink"/index.html) Installing the package

```
composer require spatie/yii-ray
```

This installs Ray as a project dependency, meaning it will also be installed in your production environment. Your application won't break if you forget to remove a `ray` call. The package doesn't send data when the environment isn't set to `dev`.

If you prefer, install it as a dev dependency by adding `--dev` to the composer command. Note that with a dev dependency, any `ray` calls left in your code will cause errors in production, so you'll need to remove them before deploying. We have some options for [detecting Ray calls](/content/docs/php/vanilla-php/detecting-removing-ray-calls/index.html) in your app.

```
composer require spatie/yii-ray --dev
```

## [#](/content/docs/php/yii/getting-started#usage "Permalink"/index.html) Usage

All [generic PHP methods](/content/docs/php/vanilla-php/usage/index.html) are available when using Yii.

To enable `ray()`, `dd()` and `dump()` globally in any file, see the [global installation instructions](/content/docs/php/vanilla-php/installation#global-installation/index.html).
