dynamicobjects | Create PHP objects having dynamic classes and/or properties

I tried and fail to adapt this code. This is dynamic class generator from assembly on C# language. I can't use DynamicObjects because RDLC report doesn't work with none class from System.Dynamic but work great with that class generated by assembly.

What I'm trying to do is to change the property definition from a private variable to a method get and set. Don't need to be a property if it work with two functions will be great.

The code below I have commented the part that I need to change.

I am currently developing a system where I have 2 dropdown list which is the model and destination. However, the destination is a dynamic dropdown list and is dependent on the model that is chosen by the user and will only be added on button click. On button click, the dynamic dropdown list, textbox and label should display one at a time depending on the chosen destination.

My problem is I've messed up my for loop because it displays all the dropdown list's values on every button click without considering the chosen dropdown list value. Please help me. I've been debugging this for a week and I'm still learning javascript/jQuery.

Here is my progress so far:

I needed the destination dropdown list to be dependent on my model's dropdown list. And whenever the user will chose an option on the destination list, textbox and label will be generated. However, I've messed up with my for loop so whenever the user adds a destination, model A.1 and model A.2 values shows up and when the user choose Model B, the destination should be of Model B's.

Please help me. Im still struggling to learn html/javascript/jquery Here is my progress so far:

I have looked at the post here How to unit test Realm migrations and am trying to implement what they have stated which is the following:

Store old .realm files and write tests for before / after migrations.

I have my v0.realm file in my unit test bundle and am creating a copy of it to work with. The issue is that with my latest migration I removed a Type from my application and thus from Realm and I'd like to test that it no longer exists.

When I set up my realm configuration I should be able to apply some objectTypes, however the class is no longer in my application and I am unsure how to check for it.

Here's my current test set up where I am trying to test that my object exists in Realm v0. Note that this is my first migration with Realm and really my first experience with Realm.

I would like to loop on a vector and filter out all the non-null-pointer elements. I'm looking for either an std function that checks for something being a nullptr or an std function that actually returns whatever is passed to it (like std::forward), since a null pointer would evaluate to false.
