You are coping what is usually refered as 'longest common subsequence problem', there are a looot of implementations of the most common algorithm. You can spot the solution of your problem working on the script provided here.
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
function
Where diff.txt would be the resulting file with the comparison between the two files.

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.
Thanks ahead for the help.

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.
