What are the potential security risks of calling a PHP page in the background?

When calling a PHP page in the background, one potential security risk is that sensitive data could be exposed if proper security measures are not in place. To mitigate this risk, it is important to sanitize user input, validate input data, and use secure coding practices to prevent SQL injection, cross-site scripting, and other vulnerabilities. 

// Example of calling a PHP page in the background with security measures in place

// Sanitize user input
$user_input = filter_var($_POST['input_data'], FILTER_SANITIZE_STRING);

// Validate input data
if (empty($user_input)) {
    die('Input data is empty');
}

// Implement secure coding practices
// Your code here to process the input data securely
