# Installation Learn how to integrate Croct into your PHP project. The following guide gives you a step-by-step overview of how to install and initialize the SDK in your project. > **Speed up your integration!** > > The CLI can fully automate the integration process for you. Check out the [integration guide](/reference/sdk/php/integration) to get started faster. ## Install the SDK \[#install] Install the SDK using [Composer](https://getcomposer.org): ```sh composer require croct/plug-php ``` The SDK works with any [PSR-18 HTTP client](https://www.php-fig.org/psr/psr-18/) and [PSR-17 factories](https://www.php-fig.org/psr/psr-17/), which it discovers automatically. If your project does not have a compatible implementation yet, install one: ```sh composer require guzzlehttp/guzzle nyholm/psr7 ``` ## Initialize the SDK \[#initialize] Add your credentials to a `.env` file in your project root: **.env** ```bash CROCT_APP_ID= CROCT_API_KEY= ``` You can find the application ID and create an API key on the [Integration page](https://app.croct.com/redirect/organizations/-organization-/workspaces/-workspace-/applications/-application-/integration) of your application. Then set up the SDK and hand off to the browser so personalization continues transparently on the client side: **index.php** ```php fetchContent('home-banner')->getContent(); Croct::emitCookies(); ?> My application

``` The [`fromDotenv`](api/core/croct/from-dotenv) factory reads the credentials from your `.env` file and uses a cookie-based session store. Calling [`emitCookies`](api/core/croct/emit-cookies) writes the session cookies before any output, while [`getPlugOptions`](api/core/plug/get-plug-options) returns the configuration the [JavaScript SDK](/reference/sdk/javascript) needs to work transparently with the same session. For more details, see [Client-side setup](client-side-setup). ## Check your integration \[#check] If you open your application now, it should start sending events. To check if your integration is working, go to the [Integration page](https://app.croct.com/redirect/organizations/-organization-/workspaces/-workspace-/applications/-application-/integration) of your application. ![Integration status](/assets/reference/sdk/integration-status.png) When working correctly, you should see a green bullet next to the **Status** label saying **"Received traffic in the past 24 hours"**. If you still do not see this message after a few minutes, see the [Troubleshooting](troubleshooting) reference. ## Explore - [PHP SDK](https://github.com/croct-tech/plug-php): Explore and contribute to the SDK development on GitHub. - [Troubleshooting](troubleshooting): Identify and resolve issues with your integration.
