PHP调用FTP

<?php
// set up basic connection
$ftp_server = ‘ftp.com‘; //FTP服务器
$ftp_user_name = ‘username‘;

$conn_id = ftp_connect($ftp_server);
 
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
 
// check connection
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";
    }
 
// 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 $ftp_server as $destination_file";
    }
 
// close the FTP stream
ftp_close($conn_id);
