Installation

You have multiple ways to install Twig.

Installing the Twig PHP package

Install Composer and run the following command:

composer require "twig/twig:^1.0"

Installing the C extension

Twig comes with an optional C extension that improves the performance of the Twig runtime engine.

Note that this extension does not replace the PHP code but only provides an optimized version of the \Twig\Template::getAttribute() method; you must still install the regular PHP code

The C extension is only compatible and useful for PHP5.

Install it like any other PHP extensions:

cd ext/twig
phpize
./configure
make
make install

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.

Finally, enable the extension in your php.ini configuration file:

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.
