What are the potential risks of using GET requests to modify data in PHP applications?

Using GET requests to modify data in PHP applications can pose security risks as GET requests are visible in the URL and can be easily manipulated by users. This can lead to unauthorized data modifications or injections. To mitigate this risk, it is recommended to use POST requests for any actions that modify data in the application. 

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Process data modification here
} else {
    // Redirect or display an error message for GET requests attempting to modify data
}
