I think the best way to deal with this problem would be sorting the 
array BEFORE it is assigned.

You can define our own sorting function for that:

function sort_pref($a,$b)
{
	if($a['Preferences']['position']==$b['Preferences']['position'])
		return 0;
	return ($a['Preferences']['position'] < $b['Preferences']['position']) 
? -1 : 1;
}

then you call usort:

usort($the_array,"sort_pref");

See also the documentation for usort.


With best regards
