What are potential pitfalls of dynamically defining class structures in PHP?

Potential pitfalls of dynamically defining class structures in PHP include making the code harder to maintain, debug, and understand. It can also lead to unexpected behavior and performance issues. To mitigate these risks, it is important to carefully plan and document the dynamic class creation process, as well as thoroughly test the code to ensure its stability. 

// Example of dynamically defining class structures in PHP with caution

// Define a base class
class BaseClass {
    public function __construct() {
        echo "BaseClass constructor called\n";
    }
}

// Dynamically create a new class extending the base class
$dynamicClassName = 'DynamicClass';
eval("class $dynamicClassName extends BaseClass {}");

// Instantiate the dynamically created class
$instance = new $dynamicClassName();
