What are the potential security risks associated with passing sensitive data through URLs in PHP applications?

Passing sensitive data through URLs in PHP applications can expose the data to potential security risks such as interception, unauthorized access, and data leakage. To mitigate these risks, sensitive data should not be passed through URLs. Instead, sensitive data should be encrypted and stored securely on the server-side, and accessed through secure methods such as sessions or POST requests. 

// Example of passing sensitive data through POST request instead of URL
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Validate username and password
    // Process login logic securely
}
