That's Perl for $str = preg_replace ("/\r\n/g", "\n", $str);

Hi all,
I am trying to implement a user-input scrubbing function, more specifically, normalize linebreaks from windows/mac to unix. I can just do preg_replace but I saw this piece of code somewhere and don't understand it enough to even know what to google.
supposedly converts Windows CRLF to Unix LF:
$str =~ s/\r\n/\n/g;
What does =~ do? I can RTFM if you point me to it :)
Never miss a thing. Make Yahoo your homepage.
