Can anyone tell me why this is outputting nothing.. at all? No errors, no notices. Nada. 
I really need help with this, theres nothing wrong with the SQL details. The codes purpose is too display Mysql data with an AJAX div that loads more posts. If theres anything that could be causing this please post below. Thanks!:)
Source code: 

```
 <?php
    /* grab stuff */
    function get_posts($start = 0, $number_of_posts = 5) {
        /* connect to the db */
        $connection = mysql_connect('localhost','root','');
        mysql_select_db('draft2',$connection) or die(mysql_error()); 
        $posts = array();
        /* get the posts */
        $query = "SELECT item_id, username, item_content FROM updates ORDER BY update_time DESC LIMIT $start,$number_of_posts" or die(mysql_error()); 

        $result = mysql_query($query);
        while($row = mysql_fetch_assoc($result)) {
            preg_match("/<p>(.*)<\/p>/",$row['item_content'],$matches);
            $row['item_content'] = strip_tags($matches[1]);
            $posts[] = $row;
        }
        /* return the posts in the JSON format */
        return json_encode($posts);
    }
