php实现的使用ftp自动更新上传文件的代码,有需要的朋友,可以参考下。
完整代码。
Mirror update
';
exit;
}
echo "Connected to $host. ";
@ $result=ftp_login($conn,$user,$password);
if(!$result)
{
echo "Error: 用户 $user 登录失败。 ";
ftp_quit($conn);
exit;
}
echo "login as $user ";
//check file times to see if an update is required
echo 'Checking file time....';
if(file_exists($localfile))
{
$localtime=filetime($localfile);
echo 'Local file last updated';
echo date('G:i j-M-Y',$localtime);
echo ' ';
}
else
$localtime=0;
$remotetime=ftp_mdtm($conn,$remotefile);// 获取远程文件的修改时间函数
if (!($remotetime>=0))
{
echo 'Can/'t access remote file time. ';
$remotetime=$localtime+1; //make sure of an update
}
else
{
echo 'Remote file last updated';
echo date('G:i j-M-Y',$remotetime);
echo ' ';
}
if(!($remotetime>$localtime))
{
echo 'Local copy is up to date. ';
exit;
}
//download file
echo 'Getting file from server.... ';
$fp=fopen($localfile,'w');
if(!$success=ftp_fget($conn,$fp,$remotefile));
{
echo 'Error:Could not download file';
ftp_quit($conn);
exit;
}
fclose($fp);
echo "File download successfully";
//close connection to host
ftp_quit($conn);
//fget()函数的用法:
//ftp_get($conn,$localfile,$remotefile);
?>
