i want to compare both $text1 and $text2 for differences and highlight
the differece in php.is it possible.
yes. is it easy? that depends on how far you want to go with diff'ing
(and how good you are at string manipulation :-)
this is a general problem which has been solved by very skilled people
already, I would suggest reading some more about 'diff' etc and
figure out if you can use existing tools to get what you want:
http://www.gnu.org/software/diffutils/diffutils.html
http://en.wikipedia.org/wiki/Diff
waiting for your reply.
thanks.
Yours,
Jenny
