PHP +only output X number of words (or letters?)
 
Code:
        function output_News($a = 5,$f = ""){
        global $db, $Data, $vbulletin;

        // Define amount to show
        $Amount = ($a)? intval($a) : 5;

        // Define Forum To Pull From
        $Forum = ($f)? intval($f): '';

                if(!$Forum){
                RunError("No specified forum to pull news from.");
                }

        // Load Template
        $Template = LoadTemplate("news.html");

        // Collect Data
        $NewestNews = $db->query("
                        select t.*,p.pagetext
                        from ".TABLE_PREFIX."thread t
                        left join ".TABLE_PREFIX."post p on(p.postid=t.firstpostid)
                        where t.forumid = $Forum
                        order by dateline desc
                        limit 0,$Amount");


        $bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());

                while($News = $db->fetch_array($NewestNews)){
                $Data .= ParseTemplate($Template,
                                                        array(
                                                                'threadid'    => $News['threadid'],
                                                                'threadname'  => $News['title'],
                                                                'postuserid'  => $News['postuserid'],
                                                                'postusername' => $News['postusername'],
                                                                'post'        => $bbcode_parser->parse(unhtmlspecialchars($News['pagetext']), $f),
                                                                'comments'    => vb_number_format($News['replycount']),
                                                        )
                        );
                }

        doOutput();
        }
I'm using VBExternal on my website, and I need to modify that little bit of code displaying the actual news post to only output a maximum of 30 words, or 190 characters.

Code:
        'post'        => $bbcode_parser->parse(unhtmlspecialchars($News['pagetext']), $f),
I used to know how to do this through php, but I havn't coded for about 10 months and I've forgotten so much :(

Figured it out, it was easier than I thought :)

Code:
'post'        => $bbcode_parser->parse(unhtmlspecialchars(substr($News['pagetext'], 0, 100)), $f),
worked :)
