<function>next</function> behaves like

<function>current</function>, with one difference. It advances
|
|
the internal array pointer one place forward before returning the
|
|
element value. That means it returns the next array value and
|
|
advances the internal array pointer by one.

You won't be able to distinguish the end of an array from a
|
|
<type>boolean</type> &false; element. To properly traverse an array
|
|
which may contain &false; elements, see the <function>each</function>
|
|
function.
