function downfile($fileurl='http://www.fuhuaqi.com/Upload/activity/mongo.rar')
{
// 下载本地方式一：会受到文件大小限制
// ob_start();
// $filename=$fileurl;
// $date=date("Ymd-H:i:m");
// header( "Content-type: application/octet-stream ");
// header( "Accept-Ranges: bytes ");
// header( "Content-Disposition: attachment; filename= {$date}.zip");
// $size=@readfile($filename);
// header( "Accept-Length: " .$size);
// 下载本地方式二：目前下载500M左右的都没问题，就是时间太慢
set_time_limit(0);
ini_set('memory_limit', '512M');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fileurl));
header('Content-Transfer-Encoding: binary');
ob_end_clean();
$size = readfile($fileurl);
header( "Accept-Length: " .$size);
}
方法三：下载之后在指定的地方，但是没有返回，成功之后只是一个空页面，使用TP的HTTP类
//下载之后在指定的地方，但是没有返回，只是一个空页面
public function downmy()
{
$tu = time() . 'mygoods' . ".zip";
$Http = new Http();
$Http->curlDownload("http://www.fuhuaqi.com/Upload/activity/111111.zip", "./Upload/activity/".$tu);
$url = "http://www.fuhuaqi.com/Upload/activity/".$tu;
return $url;
}

修改之后：
function downfile($fileurl='http://www.fuhuaqi.com/Upload/activity/mongo.rar')
{
ob_start();
set_time_limit(0);
ini_set('memory_limit', '512M');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fileurl));
header('Content-Transfer-Encoding: binary');
ob_end_clean();
$size = readfile($fileurl);
header( "Accept-Length: " .$size);
}
修改1.0.1
function downfile()
{
ob_start();
$id = I('get.id');
$bpapplys = D('Bpapply')->selectOne($id);
//上线后需要修改路径为绝对路径，否则下载不全
$fileurl="http://www.fuhuaqi.com/Upload/bpapply/".$bpapplys['bp_bpimg'];
set_time_limit(0);
ini_set('memory_limit', '512M');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fileurl));
header('Content-Transfer-Encoding: binary');
ob_end_clean();
$size = readfile($fileurl);
header( "Accept-Length: " .$size);
}
