Are there any best practices for handling multiple users accessing an FTP server using PHP?

When multiple users are accessing an FTP server using PHP, it is important to handle concurrent connections properly to avoid conflicts and ensure data integrity. One best practice is to use PHP's FTP functions in a way that each user's connection is isolated and does not interfere with others. This can be achieved by establishing separate FTP connections for each user and closing the connection after the operation is completed. 

// Example of handling multiple users accessing an FTP server using PHP

// User 1 FTP connection
$ftp_user1 = ftp_connect('ftp.example.com');
ftp_login($ftp_user1, 'user1', 'password1');

// User 2 FTP connection
$ftp_user2 = ftp_connect('ftp.example.com');
ftp_login($ftp_user2, 'user2', 'password2');

// Perform FTP operations for User 1
// ...

// Close User 1 FTP connection
ftp_close($ftp_user1);

// Perform FTP operations for User 2
// ...

// Close User 2 FTP connection
ftp_close($ftp_user2);
