What are the potential security risks of using GET requests to edit or delete data in PHP?

Using GET requests to edit or delete data in PHP can pose security risks because GET requests are visible in the browser's address bar and can be easily manipulated by users. This makes it vulnerable to Cross-Site Request Forgery (CSRF) attacks where an attacker tricks a user into unknowingly executing actions on a website they are authenticated to. To mitigate this risk, it is recommended to use POST requests for editing or deleting data as they are not visible in the address bar and provide a higher level of security. 

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Process the form data for editing or deleting data
} else {
    // Redirect to an error page or display an error message
}
