Hello Stuart,
great, thats a first success and works fast.
There are just 2 things which fail on this function:
1. Problems with full stops. A word with a full stop will be ignored (e.g
singapore. will not be found if you search for singapore)
2. If you search for singapore and there is a hit Singapore (notice the
capital!) will be replaced with singapore in the text.
I tryed to fix that, but I fear that my php experiance lacks on this stage
:-(
Maybe someone else or you do have a idea for a fix?
Cheers Andy
