json encode a multidimensional array

[jimfog]

The code was given by JamesB and I am still studying it and trying to understand how it works.

Line 17 is a hint.

Here's another clue:

The error says $appdata is undefined, so we must define it before it is used.

I defined it outside the while loop and that seems to solve the problem...

  $appdata=array();

I am going to study the code first and then ask some questions cause I want to realize here what is going on fully.

 

And again...many thanks.It was very frustrating....

it still stands to ask why you are trying to json encode before all the data is assembled. it doesn't make sense to me.

where do you see that?

I do not understand

hmm, I must have misread, but I thought I saw it happening one of the posts.

I also thought json_encode was used in a loop lol, a bracket must have fooled us both.
