What are the potential pitfalls of dynamically calling methods in PHP, as seen in the provided code examples?

One potential pitfall of dynamically calling methods in PHP is the lack of type safety and potential for runtime errors if the method being called does not exist. To mitigate this risk, it's important to validate the method existence before calling it dynamically. This can be achieved by using the method_exists function to check if the method exists in the class before invoking it. 

class MyClass {
    public function myMethod() {
        echo "Hello, World!";
    }
}

$object = new MyClass();
$method = 'myMethod';

if (method_exists($object, $method)) {
    $object->$method();
} else {
    echo "Method does not exist.";
}
