                                    current

   (PHP 3, PHP 4 )
   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 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.

   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.

   Example 1. Example use of current() and friends
   <?php
   $transport = array('foot', 'bike', 'car', 'plane');
   $mode = current($transport); // $mode = 'foot';
   $mode = next($transport);    // $mode = 'bike';
   $mode = current($transport); // $mode = 'bike';
   $mode = prev($transport);    // $mode = 'foot';
   $mode = end($transport);     // $mode = 'plane';
   $mode = current($transport); // $mode = 'plane';
   ?>

   See also end(), key(), next(), prev(), and reset().
