Note Submitter: Christo Fogelberg ---- A minor correction or two to georgesk's code of 9 March 2002: He initialises the array with: $LCS_Length_Table = array(array(128),array(128)); and then resets the relevant columns to 0, except that this doesn't create a 128-by-128 array, which I think is his intention. The code to do that is - and if anyone knows a prettier version, please post! - something like: $LCS_Length_Table = array_pad(array(), 128, array_pad(array(), 128, 0)); Alternatively, if you want to allocate only as much space as needed, but no more than 128 chars per string, then use: $LCS_Length_Table = array_pad(array(), min($m, 128)+1, array_pad(array(), min($n, 128)+1, 0)); (You need the +1 because we actually use indexes up to strlen($s1) and strlen($s2), but PHP arrays are 0-based of course). Other than that though, some very nice code! :-) Christo
