How can PHP wrappers like ftp:// and ssh2.sftp:// be utilized effectively for transferring files between servers?

To transfer files between servers using PHP wrappers like ftp:// and ssh2.sftp://, you can utilize functions like ftp_put() for FTP transfers and ssh2_scp_send() for SSH transfers. These functions allow you to upload files from one server to another securely and efficiently.

// FTP transfer example
$remoteFile = 'ftp://username:password@remote-server.com/path/to/remote/file.txt';
$localFile = '/path/to/local/file.txt';

if (ftp_put($remoteFile, $localFile, FTP_BINARY)) {
    echo "File transferred successfully via FTP";
} else {
    echo "Failed to transfer file via FTP";
}

// SSH transfer example
$remoteFile = 'ssh2.sftp://username:password@remote-server.com/path/to/remote/file.txt';
$localFile = '/path/to/local/file.txt';

if (ssh2_scp_send($remoteFile, $localFile)) {
    echo "File transferred successfully via SSH";
} else {
    echo "Failed to transfer file via SSH";
}
