How can PHP developers improve the security of their applications when implementing data deletion functionality?

When implementing data deletion functionality in PHP applications, developers can improve security by validating user permissions before allowing the deletion of data. This ensures that only authorized users can delete records, preventing unauthorized access to sensitive information. 

// Check user permissions before deleting data
if($user->isAdmin()) {
    // Perform data deletion operation
    $result = $db->query("DELETE FROM table WHERE id = $id");
    if($result) {
        echo "Data deleted successfully";
    } else {
        echo "Error deleting data";
    }
} else {
    echo "You do not have permission to delete data";
}
