# Installation You have multiple ways to install Twig. ### Installing the Twig PHP package ### Installing via Composer (recommended) Install [Composer](https://getcomposer.org/download/) [https://getcomposer.org/download/] and run the following command to get the latest version: <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1</pre></div></td><td class="code"><div class="highlight"><pre>composer require twig/twig:~1.0 </pre></div></td></tr></table> ### Installing from the tarball release 1. Download the most recent tarball from the [download page](https://github.com/twigphp/Twig/tags) [https://github.com/twigphp/Twig/tags] 1. Verify the integrity of the tarball [http://fabien.potencier.org/article/73/signing-project-releases](http://fabien.potencier.org/article/73/signing-project-releases) 1. Unpack the tarball 1. Move the files somewhere in your project ### Installing the development version <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1</pre></div></td><td class="code"><div class="highlight"><pre>git clone git://github.com/twigphp/Twig.git </pre></div></td></tr></table> ### Installing the PEAR package Note Using PEAR for installing Twig is deprecated and Twig 1.15.1 was the lastversion published on the PEAR channel; use Composer instead. <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1 2</pre></div></td><td class="code"><div class="highlight"><pre>pear channel-discover pear.twig-project.org pear install twig/Twig </pre></div></td></tr></table> ### Installing the C extension New in version 1.4: The C extension was added in Twig 1.4. Note The C extension is **optional** but it brings some nice performanceimprovements. Note that the extension is not a replacement for the PHPcode; it only implements a small part of the PHP code to improve theperformance at runtime; you must still install the regular PHP code. Twig comes with a C extension that enhances the performance of the Twigruntime engine; install it like any other PHP extensions: <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1 2 3 4 5</pre></div></td><td class="code"><div class="highlight"><pre>cd ext/twig phpize ./configure make make install </pre></div></td></tr></table> Note You can also install the C extension via PEAR (note that this method isdeprecated and newer versions of Twig are not available on the PEARchannel): <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1 2</pre></div></td><td class="code"><div class="highlight"><pre>pear channel-discover pear.twig-project.org pear install twig/CTwig </pre></div></td></tr></table> For Windows: 1. Setup the build environment following the [PHP documentation](https://wiki.php.net/internals/windows/stepbystepbuild) [https://wiki.php.net/internals/windows/stepbystepbuild] 1. Put Twig's C extension source code into `C:\php-sdk\phpdev\vcXX\x86\php-source-directory\ext\twig` 1. Use the `configure --disable-all --enable-cli --enable-twig=shared` command instead of step 14 1. `nmake` 1. Copy the `C:\php-sdk\phpdev\vcXX\x86\php-source-directory\Release_TS\php_twig.dll` file to your PHP setup. Tip For Windows ZendServer, ZTS is not enabled as mentioned in [Zend ServerFAQ](http://www.zend.com/en/products/server/faq#faqD6) [http://www.zend.com/en/products/server/faq#faqD6]. You have to use `configure --disable-all --disable-zts --enable-cli--enable-twig=shared` to be able to build the twig C extension forZendServer. The built DLL will be available in`C:\\php-sdk\\phpdev\\vcXX\\x86\\php-source-directory\\Release` Finally, enable the extension in your `php.ini` configuration file: <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1 2</pre></div></td><td class="code"><div class="highlight"><pre>extension=twig.so #For Unix systems extension=php_twig.dll #For Windows systems </pre></div></td></tr></table> And from now on, Twig will automatically compile your templates to takeadvantage of the C extension. Note that this extension does not replace thePHP code but only provides an optimized version of the`Twig_Template::getAttribute()` method.
