PHP code is not correctly showed

Following code:

function parseUrl ( $url )
{
    $r  = '!(?:(\w+)://)?(?:(\w+)\:(\w+)@)?([^/:]+)?';
    $r .= '(?:\:(\d*))?([^#?]+)?(?:\?([^#]+))?(?:#(.+$))?!i';

    preg_match ( $r, $url, $out );

    return $out;
}

pasted in php tags, it's not viewed properly, even there is no ending tag.

Example:

function parseUrl ( $url )
{
    $r  = '!(?:(\w+)://)?(?:(\w+)\:(\w+)@)?([^/:]+)?';
    $r .= '(?:\:(\d*))?([^#

+)?(?:\?([^#]+))?(?:#(.+$))?!i';

preg_match ( $r, $url, $out );

return $out;
}
?>
