无法在页面上使用php显示图片

I am trying to dynamically display a picture based on the the entry on the database. I can see i am able to build the url from where the picture has to be fetched but it doesn't display the picture.. I am not able to figure out what is happening.. any help will be appreciated.

             // Connect to the database
             $dbhost = 'localhost';
             $dbusername = 'vote';
             $dbpasswd = 'vote';
             $database_name = 'vote_active';
             $connection = mysql_connect("$dbhost","$dbusername","$dbpasswd")
              or die ('Couldn\'t connect to server.');
             $db = mysql_select_db("$database_name", $connection)
              or die('Couldn\'t select database.');

             $sqlMain = ("SELECT DISTINCT number, comments, Engineer, votes FROM active_nomination;");
             $lqlMain = mysql_query($sqlMain) or die(mysql_error());
             while($lplMain = mysql_fetch_assoc($lqlMain)){
                 $enge = utf8_encode($lplMain['Engineer']);
                //print $enge;
                $url= "http://wwwin.kabi.com/dir/photo/prof/$enge.jpg";
                print $url;
                echo
                '<td>;
                <img src="<?php $url ?>"  />
                </td>';
             }
                ?>

Change the echo line to

echo '<td><img src="'.$url.'"  /></td>';

You were not properly string concatenating. Also there is no need for wrapping variables within php tags when you are already within the PHP block.
