用php实现ftp传输

$conn_id = ftp_connect（"$your_ftp_server"）；        // login with username and password        $login_result = ftp_login（$conn_id, "$ftp_your_name", "$ftp_your_password"）；        // check connection        if （（！$conn_id） || （！$login_result）） {        echo "Ftp connection has failed!";        echo "Attempted to connect to $your_ftp_server ";        die;        } else {        echo "Connected to $ftp_server, for your";        }        // upload the file        $upload = ftp_put（$conn_id, "$destination_file", "$source_file", FTP_BINARY）；        // check upload status        if （！$upload） {        echo "Ftp upload has failed!";        } else {        echo "Uploaded $source_file to $your_ftp_server as $destination_file";        }        // close the FTP stream        ftp_quit（$conn_id）；        ?>        显然利用PHP可以方便的进行网络的文件传输，没有必要写socket程序。
