What is the purpose of using a proxy server in a Curl function in PHP?

When making HTTP requests using Curl in PHP, you may need to use a proxy server to route your requests through a different IP address for various reasons such as bypassing restrictions or improving security. This can be achieved by setting the CURLOPT_PROXY option in the Curl request to the desired proxy server address. 

// Initialize Curl
$ch = curl_init();

// Set the URL to make the request to
curl_setopt($ch, CURLOPT_URL, 'https://example.com');

// Set the proxy server address and port
curl_setopt($ch, CURLOPT_PROXY, 'proxy.example.com:8080');

// Execute the Curl request
$response = curl_exec($ch);

// Close Curl
curl_close($ch);

// Handle the response as needed
