current -- Return the current element in an array
Description
mixed current (array array)
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 array element that's currently being
pointed 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.
| Warning |
|
If the array contains empty elements (0 or "", the empty string) then this function will
return FALSE for these elements as well. This makes it impossible to determine if
you are really at the end of the list in such an array using current(). To properly traverse
an array that may contain empty elements, use the each()
function.
