Spaces and newlines in regular expressions

[Kyle]

How can I signify a space or a newline in a regular expression? Are
they just represented by whitespace and \n?

Thanks!

Yup. Although you can also use \s for a space too, useful when looking for
the likes of '\s*' or '\s{1,8}' etc etc.

Something that might help you.. although I've posted it here before:

There's a character class "\s" that matches any whitespace character.
You can also use the regex form "/regex/s" to turn on PCRE_DOTALL, so
that the dot will match the "\n" newline characters as well. Note that
newlines are platform dependant and can be "\n" or "\r\n," etc...
