current
Return the current element in an array
Description
mixedcurrent
arrayarray
Every array has an internal pointer to its "current" element,
which is initialized to the first element inserted into the
array.
The current function simply returns the
value of the array element that's currently being pointed to by the
internal pointer. It does not move the pointer in any way. If the
internal pointer points beyond the end of the elements list,
current returns &false;.
&return.falseproblem;
You won't be able to distinguish the end of an array from a
boolean &false; element. To properly traverse an array
which may contain &false; elements, see the each
function.
