What is the difference between creating a file on an FTP server and uploading a file using PHP?

Creating a file on an FTP server involves establishing a connection to the server, specifying the file name and location, and then writing the contents of the file to the server. Uploading a file using PHP typically involves sending a file from the client-side to the server-side using a form submission or AJAX request.

// Connect to FTP server
$ftp_server = "ftp.example.com";
$ftp_user = "username";
$ftp_pass = "password";
$ftp_conn = ftp_connect($ftp_server);
ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Create a file on the FTP server
$file = "example.txt";
$contents = "This is the content of the file.";
ftp_put($ftp_conn, $file, $contents, FTP_ASCII);

// Close FTP connection
ftp_close($ftp_conn);
