一些内容的file_get_contents连接超时 [英] file_get_contents Connection Timed Out for some contents

问题描述

我正在开发一个用户可以在其中上传图片的网站.

i'm developing a site in which user can upload pictures.

一旦用户插入图像的url(仅远程)，我就会将ajax调用到php并接受url并将其存储到服务器.

Once users insert the url ( only remote ) of image, i call a ajax to a php that take url and store it to the server.

问题出在file_get_contents:

The problem is the file_get_contents:

对于某些图像，它为我提供了连接超时，对于其他编号，则为我

For some images it gives me Connection Timed Out, for other no.

一些给我带来错误的图像是:

Some images that gives me that error are:

• http://www.lloydsbaiahotel.it/images/bgtop/03.jpg
• http://www.lloydsbaiahotel.it/images/bgtop/04.jpg

• http://www.lloydsbaiahotel.it/images/bgtop/03.jpg
• http://www.lloydsbaiahotel.it/images/bgtop/04.jpg

我简单地尝试以这种方式获取内容:

I simple try to fetch content in this way:

$img   = "http://www.lloydsbaiahotel.it/images/bgtop/03.jpg";
$inbuf = file_get_contents($img);
var_dump($inbuf);

可能是什么问题?我必须更改服务器的某些配置吗?

What could be the problem? Do i have to change some configurations of my server?

推荐答案

尝试使用cURL，它提供了比file_get_contents更多的选项和控件，如下所示:

try to use cURL , it gives you more options and control than file_get_contents as the following :

  $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $raw=curl_exec($ch);
    curl_close ($ch);
    $fp = fopen($save_to,'x');
    fwrite($fp, $raw);
    fclose($fp);
