What are the best practices for managing file permissions and ownership when using Joomla's installer for packages?

When using Joomla's installer for packages, it is important to manage file permissions and ownership properly to ensure security and functionality. One best practice is to set the correct permissions for files and directories to prevent unauthorized access or modification. Additionally, assigning the correct ownership of files and directories can help prevent conflicts and ensure smooth operation of the Joomla installation.

// Set the correct file permissions and ownership after installing a Joomla package
chmod('/path/to/joomla/files', 0755);
chown('/path/to/joomla/files', 'www-data');
