Connect Remote Servers using Curl with Proxy
Using curl to Connect Remote Servers
Curl and proxies
As with all other full featured browsers curl has support for proxies. Proxy
servers are buffers between the requesting client and the web server. Proxy
servers are used for a variety of reasons including companies restricting web
access to people wanting to appear anonymous.
There are a few curl options to set when using a proxy. First to enable use of a
proxy in curl use the option CURLOPT_HTTPPROXYTUNNEL. Second set
the proxy with the option CURLOPT_PROXY. If you need to set
authentication information use the option CURLOPT_PROXYUSERPWD.
CURLOPT_PROXYUSERPWD expects a string in the format of
user:password. HTTP proxies are default, to use a SOCKS proxy use the
CURLOPT_PROXYTYPE option.
Example:
$ch = curl_init();
curl_setopt($ch, CURLOPT_PROXY, ‘proxyname or no:portno’);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, ‘user:password’);
curl_setopt($ch, CURLOPT_URL, ‘http://www.sample.com’);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec();
curl_close($ch);
