PHP cURL vs. file_get_contents when using proxy - php

Question

Running in Windows.
The following code works fine. I don't have specify a username and password when setting up the proxy.
$aContext = array(
'http' => array(
'proxy' => 'tcp://ip:port',
'request_fulluri' => true,
),
);
$cxContext = stream_context_create($aContext);
echo file_get_contents("someurl", False, $cxContext);
However when I try this code it won't work unless I specify the username and password for the proxy.
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_HTTP | CURLPROTO_HTTPS);
curl_setopt($ch, CURLOPT_PROXY, 'http://ip:port');
curl_setopt($ch, CURLOPT_URL, "someurl");
$responseBody = curl_exec($ch);
I get an HTTP 407 error (Received HTTP code 407 from proxy after CONNECT) unless i specify the http://domain\user:password#ip:port
Any ideas how to make cURL work without specifying the user and password (like file_get_contents does)?

You can use the CURLOPT_PROXY and CURLOPT_PROXYPORT options:
curl_setopt($ch, CURLOPT_PROXY, "123.123.123.123");
curl_setopt($ch, CURLOPT_PROXYPORT, 8080);
It's unclear from your question, but if you need to use a username and password to authenticate with this proxy, then you can use the CURLOPT_PROXYUSERPWD option to specify your username and password and the CURLOPT_PROXYAUTH option to specify your authentication method:
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "username:password");
curl_setopt($ch, CURLOPT_PROXYAUTH, CURLAUTH_BASIC); //HTTP Basic auth
Also, depending on what type of proxy you are working with, you may need to specify the type in the CURLOPT_PROXY setting or separately via CURLOPT_PROXYTYPE.
