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');
