How can PHP be utilized to automate the process of adding date and time to webcam images uploaded to an FTP server?

To automate the process of adding date and time to webcam images uploaded to an FTP server using PHP, you can use the `imagecreatefromjpeg()` function to open the image, `imagestring()` function to add the date and time to the image, and then `imagejpeg()` function to save the modified image. Finally, you can use the `ftp_put()` function to upload the image to the FTP server.

// Load the image
$image = imagecreatefromjpeg('webcam.jpg');

// Add date and time to the image
$date = date('Y-m-d H:i:s');
imagestring($image, 5, 10, 10, $date, imagecolorallocate($image, 255, 255, 255));

// Save the modified image
imagejpeg($image, 'webcam_with_date.jpg');

// Upload the image to FTP server
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';
$local_file = 'webcam_with_date.jpg';
$remote_file = 'webcam_with_date.jpg';

$ftp_conn = ftp_connect($ftp_server);
ftp_login($ftp_conn, $ftp_user, $ftp_pass);
ftp_put($ftp_conn, $remote_file, $local_file, FTP_BINARY);
ftp_close($ftp_conn);

// Clean up
imagedestroy($image);
