You could sort it in the example given:
<?php
#arraytest.php
$ar = array( "a", "b", "c", "d", "e", "f", "g");
print_r($ar);
unset($ar[2]);
print_r($ar);
sort($ar);
print_r($ar);
?>
[bhughes@bretsony bin]$ php arraytest.php
X-Powered-By: PHP/4.1.2
Content-type: text/html
Array
(
[0] => a
[1] => b
[2] => c
[3] => d
[4] => e
[5] => f
[6] => g

Is there some reason you care that you do not have an element with the
key of 2? Remember in php all arrays are associative and not really
numerically indexed.
