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
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;.
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.
