                                   array_pad

   (PHP 4 )
   array_pad --  Pad array to the specified length with a value

Description

   array array_pad ( array input, int pad_size, mixed pad_value)

   array_pad() returns a copy of the input padded to size specified by
   pad_size with value pad_value. If pad_size is positive then the array
   is padded on the right, if it's negative then on the left. If the
   absolute value of pad_size is less than or equal to the length of the
   input then no padding takes place.

   Example 1. array_pad() example
   <?php
   $input = array(12, 10, 9);
   $result = array_pad($input, 5, 0);
   // result is array(12, 10, 9, 0, 0)
   $result = array_pad($input, -7, -1);
   // result is array(-1, -1, -1, -1, 12, 10, 9)
   $result = array_pad($input, 2, "noop");
   // not padded
   ?>
