What are the advantages and disadvantages of using GET parameters versus POST parameters for data deletion actions in PHP?

When deleting data in PHP, it is generally recommended to use POST parameters instead of GET parameters for security reasons. GET parameters are visible in the URL and can be easily manipulated, potentially leading to security vulnerabilities such as CSRF attacks. POST parameters, on the other hand, are not visible in the URL and provide a more secure way to send data to the server. 

// Example of using POST parameters for data deletion action

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if the request is coming from a trusted source
    if (isset($_POST['delete']) && $_POST['delete'] == 'true') {
        // Perform data deletion action
        $id = $_POST['id'];
        // Delete data with id $id
    } else {
        // Handle unauthorized request
        echo "Unauthorized request";
    }
}
