PHP - Re-index an array

PHP - Re-index an array 

Ever needed to re-index an array from a number that is not zero. Here is a simple helper function to get you through what can be a difficult time. If you simply needed to re-index the array beginning at zero, array_values() is the function you are looking for. If you wish to begin at one or even eighty eight, as in the example below, this is the way to go about it.


<?php
/**
 *
 * Function to re-index an array beginning at N
 *
 * @param array $array
 *
 * @param int $start
 *
 * @return @array
 *
 */
 function reIndex($start, $array)
 {
    /*** the end number of keys minus one ***/
    $end = ($start+count($array))-1;

    /*** the range of numbers to use as keys ***/
    $keys = range($start, $end);

    /*** combine the arrays with the new keys and values ***/
    return array_combine($keys, $array);
 }

  /*** an array of native australians ***/
  $animals = array("koala", "kangaroo", "platypus", "dingo", "wombat", "steve irwin", "wallaby");

  /*** re-index the array ***/
  $newArray = reIndex(88, $animals);

  /*** show the new array keys and values ***/
  foreach($newArray as $key=>$value)
 {
    echo $key." -- ".$value."<br />";
