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.

Parameters #

array

The array.

Return Values #

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 or the array is empty, current() returns FALSE.

Examples #

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';

$arr = array();
var_dump(current($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() function.
