PHP: current() function

PHP: Return the current element in an array

The current() function is used to fetch the value of the current element in an array.

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

Version:

(PHP 4 and above)

Syntax:

current(array_name)

Parameter:

Name Description Required /
Optional		 Type
array_name The input array. Required Array

Return value

The current element of array_name. If the internal array pointer is beyond the end of the elements list or the array is empty, the function returns FALSE.

Value Type : Mixed*.

*Mixed : Mixed indicates multiple (but not necessarily all) types.

Example:

<?php
$subject= array('Language','English','Math','Science');
$result = current($subject);
echo $result;
?>
