# CORS for PHP (using the Symfony HttpFoundation) [](https://github.com/fruitcake/php-cors/actions) [](https://github.com/fruitcake/php-cors/actions) [](https://github.com/fruitcake/php-cors/actions/workflows/run-coverage.yml) [](http://choosealicense.com/licenses/mit/) [](https://packagist.org/packages/fruitcake/php-cors) [](https://packagist.org/packages/fruitcake/php-cors) [](https://fruitcake.nl/) Library and middleware enabling cross-origin resource sharing for your http-{foundation,kernel} using application. It attempts to implement the [W3C Recommendation] for cross-origin resource sharing. [W3C Recommendation]: http://www.w3.org/TR/cors/ > Note: This is a standalone fork of https://github.com/asm89/stack-cors and is compatible with the options for CorsService. ## Installation Require `fruitcake/php-cors` using composer. ## Usage This package can be used as a library. You can use it in your framework using: - [Stack middleware](http://stackphp.com/): https://github.com/asm89/stack-cors - [Laravel](https://laravel.com): https://github.com/fruitcake/laravel-cors ### Options | Option | Description | Default value | |------------------------|------------------------------------------------------------|---------------| | allowedMethods | Matches the request method. | `[]` | | allowedOrigins | Matches the request origin. | `[]` | | allowedOriginsPatterns | Matches the request origin with `preg_match`. | `[]` | | allowedHeaders | Sets the Access-Control-Allow-Headers response header. | `[]` | | exposedHeaders | Sets the Access-Control-Expose-Headers response header. | `[]` | | maxAge | Sets the Access-Control-Max-Age response header. | `0` | | supportsCredentials | Sets the Access-Control-Allow-Credentials header. | `false` | The _allowedMethods_ and _allowedHeaders_ options are case-insensitive. You don't need to provide both _allowedOrigins_ and _allowedOriginsPatterns_. If one of the strings passed matches, it is considered a valid origin. A wildcard in allowedOrigins will be converted to a pattern. If `['*']` is provided to _allowedMethods_, _allowedOrigins_ or _allowedHeaders_ all methods / origins / headers are allowed. > Note: Allowing a single static origin will improve cacheability. ### Example: using the library ```php <?php use Fruitcake\Cors\CorsService; $cors = new CorsService([ 'allowedHeaders' => ['x-allowed-header', 'x-other-allowed-header'], 'allowedMethods' => ['DELETE', 'GET', 'POST', 'PUT'], 'allowedOrigins' => ['http://localhost', 'https://*.example.com'], 'allowedOriginsPatterns' => ['/localhost:\d/'], 'exposedHeaders' => ['Content-Encoding'], 'maxAge' => false, 'supportsCredentials' => false, ]); $cors->addActualRequestHeaders(Response $response, $origin); $cors->handlePreflightRequest(Request $request); $cors->isActualRequestAllowed(Request $request); $cors->isCorsRequest(Request $request); $cors->isPreflightRequest(Request $request); ``` ## License Released under the MIT License, see [LICENSE](LICENSE). > This package is split-off from https://github.com/asm89/stack-cors and developed as stand-alone library since 2022
