How was the application release carried out in the working environment?

The release of a PHP application in a production environment typically involves several stages:

1. Code preparation: Checking and testing locally or on a staging server.
2. Build (if required): For example, compiling templates, minifying scripts.
3. Deployment: Copying files to the server via FTP, SFTP, SCP, or using version control systems (Git).
4. Updating dependencies: Running composer install or similar commands on the server.
5. Database migrations: Applying changes to the database structure.
6. Caching: Clearing or updating the application's cache.
7. Restarting services (if needed): For example, PHP-FPM or web servers.

An example of a simple release using Git and SSH:

ssh user@production-server 'cd /var/www/project && git pull origin main && composer install --no-dev && php artisan migrate --force'

Thus, a release is the process of transferring tested code into the production environment with minimal downtime and risk of errors.
