Are there any best practices to follow when using PHP for file transfer scripts?

When using PHP for file transfer scripts, it is important to follow best practices to ensure security and efficiency. One key practice is to validate user input to prevent malicious file uploads or transfers. Additionally, it is recommended to use secure protocols such as SFTP or HTTPS for transferring files over the network. Finally, consider implementing error handling to gracefully handle any issues that may arise during the file transfer process. 

// Example of validating user input for file transfer script
if(isset($_FILES['file'])) {
    $file = $_FILES['file'];
    
    // Validate file type and size
    if($file['type'] == 'text/plain' && $file['size'] < 1000000) {
        // Process file transfer logic
    } else {
        echo 'Invalid file type or size';
    }
} else {
    echo 'File not found';
}
