如何在php curl中使用代理

我有一个旋度函数：

function curl($url, $referer, $type=null){
    $agent = ($type != null && $type = 'movil') ? 'Mozilla/5.0 (Linux; U; Android 4.0; en-us; GT-I9300 Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30' : 'Mozilla/5.0(Windows;U;WindowsNT5.0;en-US;rv:1.4)Gecko/20030624Netscape/7.1(ax)';
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_REFERER, $referer);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $page = curl_exec($ch);
    curl_close($ch);
    return $page;
}

但是，此功能会根据请求显示我的服务器ip，因此如果知道如何通过代理ip和端口使用它，那就太好了。谢谢

如果目的是隐藏源ip请求发起服务器的ip，那么使用curl就不可能了，因为这是一个需要操纵原始套接字连接的低级操作

如果您希望在请求某个URL时使用代理， 然后您必须使用CURLOPT_代理

function curl($url, $referer, $type=null){
    $agent = ($type != null && $type = 'movil') ? 'Mozilla/5.0 (Linux; U; Android 4.0; en-us; GT-I9300 Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30' : 'Mozilla/5.0(Windows;U;WindowsNT5.0;en-US;rv:1.4)Gecko/20030624Netscape/7.1(ax)';
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);
    curl_setopt($ch, CURLOPT_PROXY, '8.8.8.8'); // replace 
8.8.8.8' with proxy server's IP.
    curl_setopt($ch, CURLOPT_PROXYPORT, '2211'); // replace '2211' with Proxy server's port.
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_REFERER, $referer);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $page = curl_exec($ch);
    curl_close($ch);
    return $page;
}

可能重复的
