1Installation 2============ 3 4You have multiple ways to install Twig. 5 6Installing the Twig PHP package 7------------------------------- 8 9Installing via Composer (recommended) 10~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 11 12Install `Composer`_ and run the following command to get the latest version: 13 14.. code-block:: bash 15 16 composer require twig/twig:~1.0 17 18Installing from the tarball release 19~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 20 211. Download the most recent tarball from the `download page`_ 222. Verify the integrity of the tarball http://fabien.potencier.org/article/73/signing-project-releases 233. Unpack the tarball 244. Move the files somewhere in your project 25 26Installing the development version 27~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 28 29.. code-block:: bash 30 31 git clone git://github.com/twigphp/Twig.git 32 33Installing the PEAR package 34~~~~~~~~~~~~~~~~~~~~~~~~~~~ 35 36.. note:: 37 38 Using PEAR for installing Twig is deprecated and Twig 1.15.1 was the last 39 version published on the PEAR channel; use Composer instead. 40 41.. code-block:: bash 42 43 pear channel-discover pear.twig-project.org 44 pear install twig/Twig 45 46Installing the C extension 47-------------------------- 48 49.. versionadded:: 1.4 50 The C extension was added in Twig 1.4. 51 52.. note:: 53 54 The C extension is **optional** but it brings some nice performance 55 improvements. Note that the extension is not a replacement for the PHP 56 code; it only implements a small part of the PHP code to improve the 57 performance at runtime; you must still install the regular PHP code. 58 59Twig comes with a C extension that enhances the performance of the Twig 60runtime engine; install it like any other PHP extensions: 61 62.. code-block:: bash 63 64 cd ext/twig 65 phpize 66 ./configure 67 make 68 make install 69 70.. note:: 71 72 You can also install the C extension via PEAR (note that this method is 73 deprecated and newer versions of Twig are not available on the PEAR 74 channel): 75 76 .. code-block:: bash 77 78 pear channel-discover pear.twig-project.org 79 pear install twig/CTwig 80 81For Windows: 82 831. Setup the build environment following the `PHP documentation`_ 842. Put Twig's C extension source code into ``C:\php-sdk\phpdev\vcXX\x86\php-source-directory\ext\twig`` 853. Use the ``configure --disable-all --enable-cli --enable-twig=shared`` command instead of step 14 864. ``nmake`` 875. Copy the ``C:\php-sdk\phpdev\vcXX\x86\php-source-directory\Release_TS\php_twig.dll`` file to your PHP setup. 88 89.. tip:: 90 91 For Windows ZendServer, ZTS is not enabled as mentioned in `Zend Server 92 FAQ`_. 93 94 You have to use ``configure --disable-all --disable-zts --enable-cli 95 --enable-twig=shared`` to be able to build the twig C extension for 96 ZendServer. 97 98 The built DLL will be available in 99 ``C:\\php-sdk\\phpdev\\vcXX\\x86\\php-source-directory\\Release`` 100 101Finally, enable the extension in your ``php.ini`` configuration file: 102 103.. code-block:: ini 104 105 extension=twig.so #For Unix systems 106 extension=php_twig.dll #For Windows systems 107 108And from now on, Twig will automatically compile your templates to take 109advantage of the C extension. Note that this extension does not replace the 110PHP code but only provides an optimized version of the 111``Twig_Template::getAttribute()`` method. 112 113.. _`download page`: https://github.com/twigphp/Twig/tags 114.. _`Composer`: https://getcomposer.org/download/ 115.. _`PHP documentation`: https://wiki.php.net/internals/windows/stepbystepbuild 116.. _`Zend Server FAQ`: http://www.zend.com/en/products/server/faq#faqD6 117
