Now you have the $matches array with all the lines of the domain file that match the keywords
NOTE THAT WITH THE PREVIOUS APPROACH THE TWO ENTIRE FILES ARE LOADED INTO MEMORY AND DEPENDING ON THE FILE SIZES YOU CAN RUN OUT OF MEMORY OR THE OS WILL START USING THE SWAP WHICH IS MUCH SLOWER THAN RAM
THIS IS ANOTHER AND MORE EFFICIENT APPROACH THAT WILL LOAD ONE LINE IF THE FILE AT THE TIME.

You could use the Text_Diff pear package which is pretty robust. There's also the xdiff extension, which you can do this with, using the
