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