How can beginners in PHP troubleshoot and resolve issues with directory access for applications like MediaWiki?

Beginners in PHP can troubleshoot and resolve directory access issues for applications like MediaWiki by checking the file permissions on the directories where the application is trying to access or write files. Ensure that the directories have the correct permissions set to allow the PHP process to read and write files. Additionally, check if the directories are owned by the correct user and group to avoid permission denied errors. 

// Set correct permissions for the directory
chmod('/path/to/directory', 755);

// Set correct ownership for the directory
chown('/path/to/directory', 'www-data');
chgrp('/path/to/directory', 'www-data');
