keywords will be in format of:
I guess I would really like to do an array for keywords from a file and search each line of domains.txt for matches. Not sure where to start as I'm confused at the difference of preg_match, preg_match_all, and strpos and more or less when to use one over the other.

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
xdiff_file_diff
functionWhere diff.txt would be the resulting file with the comparison between the two files.
