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 :)
That is perl code which searches $str for "\r\n" and replaces it with '\n".
The same code in php would be preg_replace('/\r\n/',"\n",$str);
