Simple example of using ftp to download files in php

<?php
/**
 * ftp下载文件
 * site bbs.it-home.org
*/
function downfromftp($file){
//连接服务器
$conn_id = ftp_connect(“123.xxx.xxx.99”); //远程FTP的IP地址
//登陆
$login_result = ftp_login($conn_id, “1″, “kkk”);
//更改下载目录
if($login_result){
  $res=ftp_chdir($conn_id, “anony_ftp”);
  if(!$res){
    exit(‘更改目录失败’);
}
}
// 下载文件
$local_file = ‘down/’.$file;
$server_file = $file;
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
   ftp_close($conn_id);
   fclose($fp);
   return true;
} else {
   ftp_close($conn_id);
   fclose($fp);
   return false;
}
}
?>
