In perl, I am able to pass an array to a function.  When doing so, each of the array's indices apear to be scalar values to the function.

When passing the equivalent form of an assicitave array to perl (hash array), the values passed to the function apear to alternate between keys and values.

I am looking for this functionality in PHP, but must resort to constructing an eval() statement instead.

So what I'm suggesting is a language construct, perhaps as follows:  

array_as_argv() - which would alternate between keys and values.
array_keys_as_argv() - which would only pass the keys
array_values_as_argv() - which would only pass the values

This makes me think there might be a need for obj_as_argv(), but who knows?
