[FX.php List] A nagging question: Foreach

[Derrick Fogle]

I must be a blazing goofball... I never use a foreach loop if I expect  
only one record. If I only expect one record, I always check the  
foundcount first. If that's true, then I just extract the key  
[ $datakey = key($findResult['data']); ] and access the array  
structure directly with the key. But blegh, it's certainly more code  
to do so.
