小编php*_*eby的帖子

谁能告诉我为什么此CURL代码仅在我的本地服务器上起作用而不在实时服务器上起作用？在3种不同的主机上尝试过，没有任何效果。

实时检查所有内容1）启用了卷曲2）PHP版本尚可3）执行卷曲没有任何错误但没有结果

已经三天了，我找不到任何解决方案，请帮助。

error_reporting(1);
set_time_limit(1500);

$fname=time().'_myfile.flv';
header('Content-type: video/x-flv');
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$fname\"");

    $ch = curl_init() or die("Error");
    curl_setopt($ch, CURLOPT_USERAGENT, USERAGENT);
    curl_setopt($ch, CURLOPT_URL, $url);    
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  
    if(curl_exec($ch) === FALSE) 
    {
        die("Curl failed: " . curl_error($ch));  // Never goes here
    }

    curl_close($ch);
