PHP: next() function

PHP: Advance the internal array pointer of an array

The next() function is used to advance the internal array pointer. next() behaves like current(), with one difference. It advances the internal array pointer one place forward before returning the element value.

Version:

(PHP 4 and above)

Syntax:

next(array_name)

Parameter:

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

Return value:

The array value in the next place in the array pointed by internal array pointer, or FALSE if there are no more elements.

Value Type : Mixed*.

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

Example:

<?php
$val1 = array('Language', 'Math', 'Science', 'Geography');
$cval = current($val1);
echo "$cval <br />";
$cval = next($val1);
echo "$cval <br />";
$cval = next($val1);
echo "$cval <br />";
$cval= prev($val1);
echo "$cval <br />";
$cval= end($val1);
echo "$cval <br />";
?>

Output:

Language
Math 
Science
Math
Geography
