用PHP写FTP文件上传

<?php
$ftp_server = "*.*.*.*";
$ftp_user = "lu";
$ftp_pass = "love you";
// set up a connection or die
$conn_id = ftp_connect($ftp_server) or die("Couldn&#39;t connect to $ftp_server");
$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);
if ((!$conn_id) || (!$login_result)) {
    echo "FTP connection has failed!";
    echo "Attempted to connect to $ftp_server for user $ftp_user_name";
    exit;
} else {
    echo "Connected to $ftp_server, for user $ftp_user_name";
}
// try to login
$filename = date(&#39;Ymd&#39;) . ".xml";
$source_file = "/usr/local/IVR/sendwireless/xml/data/" . $filename; //源地址
echo $source_file;
$destination_file = "/ITC/admin/logstat/ftplog/" . $filename; //目标地址
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY) or die("Couldn&#39;t connect to $ftp_server");
ftp_quit($conn_id);
if (!$upload) {
    echo "FTP upload has failed!";
} else {
    echo "Uploaded $source_file to $ftp_server as $destination_file";
}
ftp_close($conn_id);
