Answer 1

function curl_file_get_contents($durl){
   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, $durl);
   curl_setopt($ch, CURLOPT_TIMEOUT, 2);
   curl_setopt($ch, CURLOPT_USERAGENT, _USERAGENT_);
   curl_setopt($ch, CURLOPT_REFERER,_REFERER_);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   $r = curl_exec($ch);
   curl_close($ch);
   return $r;
 }

$url = 'http://wx.qlogo.cn/mmopen/xu0fLo9waqKSTDO7j0kSO41O5Luq3LB6ozUvY4O7OsXUWNicB49fBs8nGYzoqcwGDARQZHpVuic4JSDngEVjVo10BoiaPd0iciaOb/0';
$a = curl_file_get_contents($url);
file_put_contents('uploads/2.jpg', $a);

这样子会很快。。。。

这个应该是网络原因吧，就下载一个图片，用什么方法根本感觉不到差别
