Help: regular expression pattern in preg_replace()

[innovations]

Here is my function:

<? function nl2p($str)
{
  return str_replace('<p></p>', '', '<p>' . preg_replace('#\n|\r#', '</p>$0<p>', $str) . '</p>');
}
?>

I need to change the regular expression pattern #\n|\r# to something that will only wrap paragraph tags around carriage returns and not new lines.

Although this may not be the solution, here is part of your problem.

Your regex allows for alternation on new lines and carriage returns. Take out the \n| in your regex to eliminate new line.

Also, nothing will go into $0 since backreferences start with 1.

That doesn't appear to change anything in my source code. I deleted all offline files in i.e. just to make sure I was reloading the page.
