What are some best practices for securely accessing network resources in PHP scripts?

When accessing network resources in PHP scripts, it is important to ensure that the connection is secure to prevent unauthorized access or data breaches. One best practice is to use HTTPS instead of HTTP to encrypt the data being transmitted. Additionally, using secure authentication methods such as OAuth or API keys can help verify the identity of the user accessing the network resources. 

// Example of securely accessing network resources in PHP using HTTPS and authentication

// Set the URL of the network resource
$url = "https://example.com/api/resource";

// Set the authentication token
$token = "your_api_token_here";

// Create a cURL session
$ch = curl_init();

// Set cURL options for HTTPS and authentication
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Authorization: Bearer $token"
));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Disable SSL verification for testing purposes

// Execute the cURL session
$response = curl_exec($ch);

// Close the cURL session
curl_close($ch);

// Process the response from the network resource
echo $response;
