For a very 'loose' email address validator, does the following regex need the backslash before the dot?
^\S+@\S+\.\S+$
(Checks for anything@anything.anything but I'm gonna change that to anything.anything to make it even 'looser')
I tested with and without the backslash using rubular.com and it seems superfluous but I'd like a second opinion or two please.
ALSO: does rubular.com use the right engine to be correct for php? I hope so coz it's the first time I've been able to fully understand some regexes I've been blindly implementing for some time!
Many thanks in advance
