 ## Cache
 
 What makes Symfony a bit special for shipping it into a PHAR is its compilation step. Indeed, the Symfony container can
 be dumped depending on multiple parameters such the application environment, whether it is in debug mode or not and if
 the cache is fresh.

+A PHAR, however, is a readonly only environment, which means the container _cannot_ be dumped once inside the PHAR. To
 prevent the issue, you need to make sure of the following:
 
 - The cache is warmed up before being shipped within the PHAR
 - The application within the PHAR is running in production mode
