How can PHP developers implement proper authorization and authentication mechanisms to safeguard against unauthorized data deletion?

To safeguard against unauthorized data deletion, PHP developers can implement proper authorization and authentication mechanisms by verifying the user's identity and permissions before allowing any deletion operations to occur. This can be achieved by checking the user's credentials, role, or permissions against the required criteria before executing any delete queries in the database.

// Check if the user is authenticated and has the necessary permissions to delete data
if($user_authenticated && $user_permissions === 'admin'){
    // Proceed with the deletion operation
    $delete_query = "DELETE FROM table_name WHERE id = $id";
    $result = mysqli_query($connection, $delete_query);
    if($result){
        echo "Data deleted successfully.";
    } else {
        echo "Error deleting data.";
    }
} else {
    echo "Unauthorized access.";
}
