Hi!

Some question about array.

- An array mantains always the order of item as inserted also if I use
string keys?
Or the items are "sorted" cause the hash of the key?
I hope to be clear for this question :)

- Can I know if a key is used?
Something like in_array() but for the key, not for the value.

- Can I remove an item from an array?

Thanks
