What are the best practices for handling network-related information in PHP applications?

When handling network-related information in PHP applications, it is important to ensure that data is securely transmitted over the network and that sensitive information is not exposed. Best practices include using secure protocols like HTTPS, validating input data to prevent injection attacks, and properly sanitizing and escaping user input. 

// Example of using cURL to securely transmit data over HTTPS
$url = 'https://example.com/api';
$data = array('key1' => 'value1', 'key2' => 'value2');

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
