$ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_PROXY, $proxy); // $proxy is ip of proxy server
 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
 curl_setopt($ch, CURLOPT_TIMEOUT, 10);
 $httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time
 echo '<br> curl'.$ch; //this line outputs resource id#5
 $exec = stripslashes(curl_exec($ch)); 
 echo '<br> exec'.curl_exec($ch); //this results blank

我很困惑为什么$exec不返回任何东西，我是新来的curl请帮助，提前感谢

curl_exec将在请求失败时返回false。

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy); // $proxy is ip of proxy server
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);

$httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time
$response = curl_exec($ch);

if ($response === false) 
    $response = curl_error($ch);

echo stripslashes($response);

curl_close($ch);

这样你会看到 curl 错误

您试图在实际执行HTTP调用之前访问HTTP响应代码。请按如下所示反向执行：

$response = curl_exec($ch);
$httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time

试试看：

curl_setopt($ch, CURLOPT_TIMEOUT, 50);

也许响应比10长。
我也遇到过同样的问题，我这样解决了。

结果返回0表示您无法连接到服务器，因此请重新检查您的代理并增加超时时间：）
