I'm not sure on that terminology. Many languages / environments have 
"sparse" arrays, arrays with negative indexes, and other variants. It's 
true that PHP's "array" type goes well beyond those, but we're talking 
about more than "non-associative" here (or I hope we are).

I think possibly the best term would be "list" - a collection where 
order is preserved, but there is no separate notion of keys: on a 
"list-like array", $foo[42] can be seen as "access the 43rd value", not 
"access the value with key 42".
