I need a word filter system for a text, however, I do not think I can find any way to differentiate between uppercase and lowercase letters. Text example:
FoGo is high! How am I going to delete this Phono? Is the fOGo high?
I need her to filter the word fire and replace it with water. The result would be:
The water is high! How can I erase this water? Is the water high?
NOTE: The words to be filtered are in a table in the database.
