Spaces and newlines in regular expressions

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

Thanks!

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...
