分享一个php上传单个文件到ftp服务器的简单例子。

代码：

<?php
/**

*/
// FTP连接参数
$host = 'ftp.xxx.com';
$usr = 'user';
$pwd = 'password';
  
// 用于上传的文件:
$local_file = './example.txt';
$ftp_path = '/data/example.txt';
  
// 连接ftp
$conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");
  
// 发送连接参数
ftp_login($conn_id, $usr, $pwd) or die("Cannot login");
  
// turn on passive mode transfers (some servers need this)
// ftp_pasv ($conn_id, true);
  
// perform file upload
$upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII);
  
// 检测上传状态:
print (!$upload) ? 'Cannot upload' : 'Upload complete';
print "n";
  
/*
** Chmod the file (just as example)
*/
  
// If you are using PHP4 then you need to use this code:
// (because the "ftp_chmod" command is just available in PHP5+)
if (!function_exists('ftp_chmod')) {
   function ftp_chmod($ftp_stream, $mode, $filename){
        return ftp_site($ftp_stream, sprintf('CHMOD %o %s', $mode, $filename));
   }
}
  
// try to chmod the new file to 666 (writeable)
if (ftp_chmod($conn_id, 0666, $ftp_path) !== false) {
    print $ftp_path . " chmoded successfully to 666n";
} else {
    print "could not chmod $filen";
}
  
// close the FTP stream
ftp_close($conn_id);
?>
