php ftp_get和奇怪的问题，在线等

[xiefangzhen]

在对方unix服务器上下载数据，文件大小都能读出来，就是内容下载不了，什么原因呀，错误提示如下
501
Warning: ftp_get() [function.ftp-get]: Opening ASCII mode data connection for 50001_Award_8_514772.txt (501 Bytes).

501的意思是：Syntax error in parameters or arguments.

贴下你的代码

可能是因为防火墙，在ftp_get()之前加上ftp_pasv($resource, true);

原文摘自php网站文档的注释：http://php.net/manual/en/function.ftp-put.php
========================================================================
If when using ftp_put you get the one of the following errors:

Warning: ftp_put() [function.ftp-put]: Opening ASCII mode data connection

Warning: ftp_put() [function.ftp-put]: Opening BINARY mode data connection

and it creates the file in the correct location but is a 0kb file and all FTP commands thereafter fail. It is likely that the client is behind a firewall. To rectify this use:

<?php
ftp_pasv($resource, true);
?>

Before executing any put commands. Took me so long to figure this out I actually cheered when I did :D

set_time_limit(600);

$conn_id = ftp_connect($ftp_server,"8221") or die("Couldn't connect to $ftp_server");
ftp_login($conn_id,"sctest","222333");
ftp_pasv($conn_id, true);
echo ftp_get($conn_id,"abc.txt","/201007/02/50001_Award_8_514772.txt",FTP_ASCII);
