How reload Twig cache in Symfony 2

Question

I have a application which is developed in PHP using the Symfony 2 framework. I have changed a HTML file, but the change is not reflecting when I refresh the page.

1. I restarted the server. No luck.

2. I tried to remove the Twig folder from the /protected/cache/ page itself. This is not loading.

How can I reload the Twig cache?

Notes:

• I am using tomcat server to deploy.
• I don’t have the Symfony 2 command line configured on the server.
• I am new to PHP.

Answer 1

The most simple way, type the command :

rm -rf app/cache/* 

The point is: all files in app/cache/ can be removed freely, they are regenerated when needed.

If you really want to clear only twig cache :

rm -rf app/cache/<environment>/twig 

Replace <environment> by dev, prod, or test according to your requirements.

Answer 2

When creating a new Twig_Environment instance, you can pass an array of options as the constructor second argument. One of them is auto_reload. When developing with Twig, it's useful to recompile the template whenever the source code changes. If you don't provide a value for the auto_reload option, it will be determined automatically based on the debug value.

Set auto_reload to be true:

$twig = new Twig_Environment($loader, array('auto_reload' => true));
