${{ variable.param.name }} = {{ variable.param|getValue:variable.form:true }};
{{ call.result}} = ;

Description #

mixed next ( array &$array )

next() behaves like current(), with one difference. It advances the internal array pointer one place forward before returning the element value. That means it returns the next array value and advances the internal array pointer by one.

Parameters #

array

The array being affected.

Return Values #

Returns the array value in the next place that's pointed to by the internal array pointer, or FALSE if there are no more elements.

Examples #

Example #1 Example use of next() and friends

<?php
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); // $mode = 'foot';
$mode = next($transport);    // $mode = 'bike';
$mode = next($transport);    // $mode = 'car';
$mode = prev($transport);    // $mode = 'bike';
$mode = end($transport);     // $mode = 'plane';
?>

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.
