How can PHP scripts be optimized to speed up the process of transferring data between FTP servers?

To optimize PHP scripts for faster data transfer between FTP servers, one can utilize passive mode for FTP connections, limit the number of FTP connections opened simultaneously, and use binary transfer mode for non-text files. Additionally, optimizing the code by reducing unnecessary loops and ensuring efficient error handling can also improve the speed of data transfer. 

// Example PHP code snippet to optimize data transfer between FTP servers
$localFile = 'local_file.txt';
$remoteFile = 'remote_file.txt';

$ftpServer = 'ftp.example.com';
$ftpUser = 'username';
$ftpPass = 'password';

$ftpConn = ftp_connect($ftpServer);
ftp_login($ftpConn, $ftpUser, $ftpPass);
ftp_pasv($ftpConn, true); // Enable passive mode

ftp_get($ftpConn, $localFile, $remoteFile, FTP_BINARY); // Use binary transfer mode for non-text files

ftp_close($ftpConn);
