# current

(PHP 3, PHP 4, PHP 5)

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`.

> 注: 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.

範例 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(), reset(), and each().
