uh, who's nit picking now? ;) Actually it's an important distinction, 
anyone talking about a "row" in an array is maybe confused about what 
is going on in general. Makes technical communication difficult...

Also if you read the PHP docs you'll see that its all key=>value when it 
comes to arrays, even so-called 'linear' arrays which are really just 
associative arrays with consecutive integers for keys. PHP does not 
have regular arrays like most languages. This is one of its 
"interesting features" - read the docs for the each() function to taste 
the insanity http://us4.php.net/each

or you could look at this, first 2 sentences:
http://www.php.net/manual/en/language.types.array.php
"An array in PHP is actually an ordered map. A map is a type that maps 
values to keys."

I don't know or care what they do with arrays internally. It's not a 
regular hash since they are ordered.
