What are the potential security risks of passing sensitive data like passwords through Ajax calls in PHP?

Passing sensitive data like passwords through Ajax calls in PHP can pose security risks such as exposing the data to potential interception by malicious actors. To mitigate this risk, it is recommended to use encryption techniques such as SSL/TLS to secure the data transmission. Additionally, sensitive data should be stored securely on the server side and never included in the URL parameters of the Ajax request. 

// Example of sending sensitive data securely through Ajax call in PHP using SSL/TLS

// Set the URL of the Ajax endpoint
$url = "https://example.com/ajax_endpoint";

// Set the sensitive data to be sent
$password = "sensitive_password";

// Create an array with the sensitive data
$data = array('password' => $password);

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

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Disable SSL verification for testing purposes

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

// Close cURL session
curl_close($ch);

// Handle the response from the Ajax endpoint
if($response) {
    echo "Response: " . $response;
} else {
    echo "Error: " . curl_error($ch);
}
