PHP: CURL is enabled but has no effect
提问by Kasim Rangwala
I'm trying to get data from external website using cURLin PHPbut, somehow it's not working.
I've checked out that CURLenable in phpinfo(). It shows cURLis enabled 
我正在尝试使用cURLin从外部网站获取数据，PHP但不知何故它不起作用。
我已经CURL在phpinfo(). 显示cURL已启用
But, my code is not working.
但是，我的代码不起作用。
<?php
if (! function_exists ( 'curl_version' )) {
exit ( "Enable cURL in PHP" );
}
$ch = curl_init ();
$timeout = 0; // 100; // set to zero for no timeout
$myHITurl = "http://www.google.com";
curl_setopt ( $ch, CURLOPT_URL, $myHITurl );
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
$file_contents = curl_exec ( $ch );
if (curl_errno ( $ch )) {
echo curl_error ( $ch );
curl_close ( $ch );
exit ();
}
curl_close ( $ch );
// dump output of api if you want during test
echo "$file_contents";
?>
It goes timeout.
它超时。
I'm not using WAMP or XAMPP server. The above code runs directly on the server. I've no idea what's going wrong.
我没有使用 WAMP 或 XAMPP 服务器。上面的代码直接运行在服务器上。我不知道出了什么问题。

Your code is perfect, I have tested it on my own server (data center in Texas) and it worked fine.
您的代码很完美，我已经在我自己的服务器（德克萨斯州的数据中心）上对其进行了测试，并且运行良好。
My guess is that your server IP is banned. Try to fetch a different URL, and see if it works for you. If it does then you are banned, if it doesn't then it might be a firewall configuration issue in your server.
我的猜测是您的服务器 IP 被禁止。尝试获取不同的 URL，看看它是否适合您。如果是，那么您将被禁止，如果不是，则可能是您的服务器中的防火墙配置问题。
