Manupilating a string in PHP

Hello everyone. I have a string that looks like this

(Mango, fruits, and), (Maize, cereals, and), (Mango juice, beverages, and)

I would like to convert the above string using php to something similar to this:

(Mango[fruits]) AND (Maize[cereals]) AND (Mango juice[beverages])

How can i achieve this in php. I have looked at PHP string replace, substr functions but cannot figure out how to use them to solve my problem. Thanking you in advance
