Turned my previous post into a function:
<?php
function ensure (&$a, $filler = '') {
// given: array $a with numerical keys
// return: $a with keys sorted numerically and any gaps filled-in
$highest = max(array_keys($a));
for ($i = 0; $i <= $highest; ++$i):
if (! isset($a[$i])):
$a[$i] = $filler;
endif;
endfor;
ksort ($a);
} // end function ensure
// usage:
// ensure($foo);
// ensure($bar, 0);
?>
