Question

I need to clear my doctrine’s cache in Symfony.

There must be some way in command line for clear the cache.

Or where should I find and delete the files belonging to cache?

Answer 1

For Symfony 3+:

 php bin/console

will list all commands, the following are relevant for cache:

 php bin/console doctrine:cache:clear-metadata 
 php bin/console doctrine:cache:clear-query  
 php bin/console doctrine:cache:clear-result

Before Symfony 3:

app/console

will list how you can do it

 app/console doctrine:cache:clear-metadata 
 app/console doctrine:cache:clear-query  
 app/console doctrine:cache:clear-result
