What potential pitfalls should be considered when using $this->lay->anmelden(); in PHP?

When using $this->lay->anmelden(); in PHP, a potential pitfall to consider is that the method may not exist in the object referenced by $this->lay. This could result in a fatal error if the method is not defined in the object or if $this->lay is not an object at all. To avoid this issue, it is important to check if the method exists before calling it using method_exists(). 

if (is_object($this->lay) && method_exists($this->lay, 'anmelden')) {
    $this->lay->anmelden();
} else {
    // handle the case where the method does not exist or $this->lay is not an object
}
