The easiest way to install the extension is via » PECL
pecl install ds
You can also build directly from source:
# Dependencies you might need to install # sudo apt-get install git build-essential php7.0-dev git clone https://github.com/php-ds/extension "php-ds" cd php-ds # Build and install the extension phpize ./configure make make install # Clean up the build files make clean phpize --clean
If you're on Windows, you can » download a compiled .dll on PECL
Note:
If you're using Composer, it's highly recommended that you include » php-ds/php-ds in your project so that your code is still functional in an environment where the extension is not installed. The extension will take priority if installed.
