You can read about it in more detail [in this blog post](https://medium.com/p/9dda7af674cd) which highlights the API, performance (relative to PHP 7) and other benefits of using the extension. Documentation ------------- [](#documentation) Documentation is available on [php.net](https://www.php.net/manual/en/book.ds.php). You should also include the [polyfill](https://github.com/php-ds/polyfill) in your project for IDE integration. Installation ------------ [](#installation) The easiest way to install the extension is to use PECL: ``` pecl install ds ``` If you're on Windows, you can download a compiled `.dll` on [PECL](https://pecl.php.net/package/ds) or under [releases](https://github.com/php-ds/extension/releases). Enabling the extension ---------------------- [](#enabling-the-extension) You'll need to add `extension=ds.so` to your primary `php.ini` file. If you encounter an "undefined symbol" error, see [\#2](https://github.com/php-ds/extension/issues/2#issuecomment-181855047). ``` # To see where .ini files are located php -i | grep "\.ini" ``` --- You can also enable the extension temporarily using the command line: ``` php -d extension=ds.so ``` **Note**: Windows would use `php_ds.dll` instead. Testing ------- [](#testing) There is a suite of PHPUnit tests that can be installed using [**Composer**](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx). ``` composer install # Install the test suite composer test # Run the tests composer memtest # Run the tests checking for memory leaks ``` Compatibility ------------- [](#compatibility) You may include the [polyfill](https://github.com/php-ds/polyfill) as a dependency in your project. This allows your codebase to still function in an environment where the extension is not installed. Contributing ------------ [](#contributing) For local development, I'm using Docker: ``` ./dev.sh # opens a shell into a development environment phpize ./configure make make install composer install composer test ``` Please see [CONTRIBUTING](CONTRIBUTING.md) for more information.
