What are the advantages and disadvantages of using File Alteration Monitor (FAM) for managing file transfers in an Intranet setting compared to other methods like Rsync or FTP?

Issue: File Alteration Monitor (FAM) can be advantageous in an Intranet setting for managing file transfers as it allows for real-time monitoring of file changes and can trigger actions based on those changes. However, FAM may have limitations in terms of scalability and compatibility with certain operating systems compared to other methods like Rsync or FTP.

// Example PHP code snippet for using File Alteration Monitor (FAM) for managing file transfers in an Intranet setting

// Connect to FAM server
$fam = fam_open();

// Monitor a directory for file changes
$filename = "/path/to/directory";
$fam_monitor = fam_monitor_directory($fam, $filename);

// Check for file changes and take action accordingly
while (true) {
    $event = fam_next_event($fam_monitor);
    if ($event['code'] == FAMChanged) {
        // Perform file transfer or other actions
    }
}

// Close FAM connection
fam_close($fam);
