[wp-hackers] Why in the heck won't this work?

Makes sense.

You are looking for a key value that doesn't exist, because the array 
key is created not by category id (wouldn't be unique), but numerically. 
You will have to either do an array_filter function which will iterate 
through each element and check the objects for the id or do a manual 
looping. No other way around it, unless you either want to use SQL, or 
ask for arrays instead of objects. The latter is possible, but the 
specifics eludes me at this moment and I lack time to find the answer 
for you.

It is highly likely that the function you are looking for has a third 
parameter for returning array.
