The issue ain't related to the conversion, it's you logic that is flawed.

But it's your foreach loop that makes you to have duplicates in your 
example in the same way as in the small example file. Take some time and 
think about what happens in each iteration, when you know what "$MyObj[] 
=" means, then you can make the proper changes in your own code.

I would also think you could simplify the whole thing for example a lot 
of the data is static, just set that data once not each time in a 
foreach loop and also as Arno already pointed out, don't add a single 
value as an array, you just make things more complex than they need to be.

Remember to not use input type="hidden" for information a user already 
have posted to you, those goes into the session, the only thing would be 
an identifier that is unique for this transaction. Prices you should 
never take from post values, only the amount of items, for if you start 
trust the posted values, I will be able to buy everything you have for 0 
bucks.
