CURRENT(3)								 1								CURRENT(3)

current - Return the current element in an array

SYNOPSIS
       mixed current (array  &$array)

DESCRIPTION
	Every array has an internal pointer to its "current" element, which is initialized to the first element inserted into the array.

PARAMETERS
	      o $array
		- The array.

RETURN VALUES
	The  current(3)  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  or	the  array  is	empty,	current(3)
       returns FALSE.

       Warning

	      This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
	      Booleans for more information. Use the === operator for testing the return value of this function.

EXAMPLES
       Example #1

	      Example use of current(3) 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';

	      $arr = array();
	      var_dump(current($arr)); // bool(false)

	      $arr = array(array());
	      var_dump(current($arr)); // array(0) { }
	      ?>

NOTES
       Note

	       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(3) function.
