How can one effectively work around firewall restrictions when using curl in PHP?

To work around firewall restrictions when using curl in PHP, you can set the CURLOPT_PROXY option to route your requests through a proxy server that is not blocked by the firewall. This allows you to bypass the restrictions and access the desired resources. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com");
curl_setopt($ch, CURLOPT_PROXY, "http://proxy.example.com:8080");
$result = curl_exec($ch);
curl_close($ch);

echo $result;
