CSV upload, once uploaded to a temp folder overwrite the existing database

Dod gammit! Upon pasting the code into Netbeans, it became apparent where the problem was.

I had:

Code:

$insert_str = rtrim($insert_data, ','); // $insert_data?? What the...?

and it should've been:

Code:

$insert_str = rtrim($insert_str, ',');

Again, I've edited my code. Please try it again. If that doesn't work, I'll continue setting up my test environment.
