Symfony2 how to clear the cache correctly?

Question

symfony

Good day!
Problem:
1) I'm a beginner developer and I'm just starting to learn OOP, PHP, its frameworks, etc.
2) I was given a site on symfony 2 for revision and I am completely confused, because its structure is quite complicated for a beginner.
3) I need to change the content of several pages (add a jquery slider and fix the location of several elements [and if everything was decided by css] ).
4) I realized that I need to edit the twig files of the pages, but nothing happens when they change! (the code changes - the page remains untouched).
5) In my opinion, it's all about the cache, but I don't know how to clean it properly.
Help me please!

Answer 1

when editing code, use a different entry point (app_dev.php).
the cache is cleared from the console:
app/console cache:clear
for production, you need to specify the environment by adding the --env=prod parameter. By default, all console commands are run in the dev environment.
The resulting command will be
app/console cache:clear -e=prod.
Another small bonus - you can write the names of the teams not to the end. For example
, app/console cach/cl - the main thing is that what is written is enough to select the desired command.

Answer 2

go to the app folder, there you will see the cache folder. Just delete it (cache folder) and that's it. Refresh page, cache cleared

Answer 3

google > bash
google > PuTTY (ssh client)
You can open the app/cache folder and delete its contents (but not the cache folder itself).
In order not to constantly clear the cache, you can go to the site via site.com/app_dev.php
If the project is being edited on a remote server, this file must be edited by deleting these lines:
if (isset($_SERVER['HTTP_CLIENT_IP'])
|| isset($ _SERVER['HTTP_X_FORWARDED_FOR'])
|| !in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', 'fe80::1', '::1'))
) {
header('HTTP/ 1.0 403 Forbidden');
exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}
