Data Structures for PHP 7

Build Status Build status PECL

An extension providing specialized data structures as efficient alternatives to the PHP array. You can read about it in more detail in this blog post which highlights the API, performance and other benefits of using the extension.

Documentation

Documentation is available on php.net. You should also include the polyfill in your project for IDE integration.

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 or under releases.

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.

# 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

There is a suite of PHPUnit tests that can be installed using Composer.

composer install   # Install the test suite
composer test      # Run the tests
composer memtest   # Run the tests checking for memory leaks

Compatibility

You may include the polyfill as a dependency in your project. This allows your codebase to still function in an environment where the extension is not installed.
