PHP prev() Function Usage and Example

PHP Array Function Manual

The prev() function moves the internal pointer of the array back one position

Syntax

prev ($array);

Definition and Usage

The prev() function returns the value of the array at the previous position pointed to by the internal array pointer, or FALSE if there are no other elements.

prev() and next() behave similarly, except that it moves the internal pointer back one position instead of forward one.

Parameter

Return Value

Returns the value of the previous element within the array, or FALSE if there are no more elements.

Online Example

<?php
　　　$input = array('foot', 'bike', 'car', 'plane');
　　　
　　　$mode = current($input);
　　　print "$mode <br　/>";
　　　
　　　$mode = prev($input);
　　　print "$mode <br　/>";
　　　
?>

Output Result:

foot
