[php] Re: [URL][/URL] tags?

[David Danier]

schau dir mal die funktion an:
(ist aus unserem forum - www.phpbb.com - hab mir aber nicht die mühe gemacht 
jetzt genau des was du brauchst rauszuschreiben, weil ich gleich weg muss)

function bbencode($message, $is_html_disabled) {

        // pad it with a space so we can distinguish between FALSE and 
matching the 1st char (index 0).
        // This is important; bbencode_quote(), bbencode_list(), and 
bbencode_code() all depend on it.
        $message = " " . $message;

        // First: If there isn't a "[" and a "]" in the message, don't bother.
        if (! (strpos($message, "[") && strpos($message, "]")) )
        {
                // Remove padding, return.
                $message = substr($message, 1);
                return $message;
        }

        // [CODE] and [/CODE] for posting code (HTML, PHP, C etc etc) in your 
posts.
        $message = bbencode_code($message, $is_html_disabled);

        // [QUOTE] and [/QUOTE] for posting replies with quote, or just for 
quoting stuff.
        $message = bbencode_quote($message);

        // [list] and [list=x] for (un)ordered lists.
        $message = bbencode_list($message);

        // [b] and [/b] for bolding text.
        $message = preg_replace("/\[b\](.*?)\[\/b\]/si", "<!-- BBCode Start 
--><B>\\1</B><!-- BBCode End -->", $message);

        // [i] and [/i] for italicizing text.
        $message = preg_replace("/\[i\](.*?)\[\/i\]/si", "<!-- BBCode Start 
--><I>\\1</I><!-- BBCode End -->", $message);

        // [img]image_url_here[/img] code..
        $message = preg_replace("/\[img\]([^?]*?)\[\/img\]/si", "<!-- BBCode 
Start --><IMG SRC=\"\\1\" BORDER=\"0\"><!-- BBCode End -->", $message);

        // Patterns and replacements for URL and email tags..
        $patterns = array();
        $replacements = array();

        // [url]xxxx://www.phpbb.com[/url] code..
        $patterns[0] = "#\[url\]([a-z]+?://){1}(.*?)\[/url\]#si";
        $replacements[0] = '<!-- BBCode u1 Start --><A HREF="\1\2" 
TARGET="_blank">\1\2</A><!-- BBCode u1 End -->';

        // [url]www.phpbb.com[/url] code.. (no xxxx:// prefix).
        $patterns[1] = "#\[url\](.*?)\[/url\]#si";
        $replacements[1] = '<!-- BBCode u1 Start --><A HREF="http://\1"

        // [url=xxxx://www.phpbb.com]phpBB[/url] code..
        $patterns[2] = "#\[url=([a-z]+?://){1}(.*?)\](.*?)\[/url\]#si";

        $message = preg_replace($patterns, $replacements, $message);

        // Remove our padding from the string..
        $message = substr($message, 1);
        return $message;

} // bbencode()
