I think I *may* have solved this at my end.
The following statement seems to work:
preg_match_all('/([\w\-]+?|[(]|[)]|\".+\")/U',strtoupper($prep_sql),$sqlarr)
;
I need to test it out with a whole series of different possible combinations
to see if it behaves the way I want it to, but so far the results are good.
If anyone can see any flaws, I'd love to know about them!
Many thanks,
Murray
