What are the potential pitfalls of accessing non-existent properties in PHP?

Accessing non-existent properties in PHP can lead to errors or unexpected behavior in your code. To avoid this issue, you can use the `isset()` function to check if a property exists before trying to access it. This way, you can prevent errors and handle the situation appropriately. 

// Check if the property exists before accessing it
if(isset($object->nonExistentProperty)){
    // Access the property if it exists
    echo $object->nonExistentProperty;
} else {
    // Handle the case where the property doesn't exist
    echo "Property does not exist";
}
