How can PHP developers troubleshoot FTP issues related to file permissions?

FTP issues related to file permissions can be troubleshooted by checking the permissions of the files and directories being accessed. PHP developers can use the `chmod()` function to change the permissions of files and directories to ensure they are set correctly for the FTP user. Additionally, developers can check the ownership of the files and directories to make sure they are owned by the FTP user. 

// Set the correct permissions for a file
$filename = 'example.txt';
$ftp_user = 'ftpuser';
$ftp_group = 'ftpgroup';
$permissions = 0644; // Set permissions to rw-r--r--

chown($filename, $ftp_user);
chgrp($filename, $ftp_group);
chmod($filename, $permissions);
