Installation

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.
