Although I've never personally used it, I believe usort() is what you
need:
http://www.php.net/manual/en/function.usort.php
You would need to create a callback function, something like:
function cmp($a, $b) {
if ($a->fieldNo == $b->fieldNo) { return 0; }
return ($a->fieldNo > $b->fieldNo) ? 1 : -1;
}
usort($structArray, 'cmp');

Thanks for the reply. I had already tried usort previously. For some reason, there
is no data for the array fields at all in the cmp function - not sure why. Does
anyone know? All help is appreciated! Thanks.
