I'm playing about with a stop words within my code I have an array full of words that I'd like to check, and an array of words I want to check against.

At the moment I'm looping through the array one at at a time and removing the word if its in_array vs the stop word list but I wonder if there's a better way of doing it, I've looked at array_diff and such however if I have multiple stop words in the first array, array_diff only appears to remove the first occurrence.

The focus is on speed and memory usage but speed more so.

Thanks
