How can PHP beginners effectively implement SSL encryption for their contact forms without relying on third-party services?

To effectively implement SSL encryption for contact forms in PHP without relying on third-party services, beginners can use the PHP's built-in functions for handling SSL connections. By setting up a secure connection using cURL and verifying the SSL certificate, data submitted through the contact form can be encrypted and securely transmitted to the server. 

<?php

// URL of the form processing script
$url = 'https://example.com/contact-form-handler.php';

// Data to be submitted through the contact form
$data = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'message' => 'This is a test message'
);

// Initialize cURL session
$ch = curl_init($url);

// Set cURL options for SSL encryption
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);

// Set cURL options for POST request
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

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

// Close cURL session
curl_close($ch);

// Process the response from the server
if ($response === false) {
    echo 'Error: ' . curl_error($ch);
} else {
    echo 'Form submitted successfully!';
}

?>
