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.
