每行仅显示 3 个 foreach 结果

我有如下脚本

$output="<table class='products'><tr>"; 
while($info = mysql_fetch_array( $data )) { 
    //Outputs the image and other data
    $output.= "<td>
    <img src=http://localhost/zack/sqlphotostore/images/"   .$info['photo'] ." width=323px ></img> 
    <b>Name:</b> ".$info['name'] . "
    <b>Email:</b> ".$info['email'] . " 
    <b>Phone:</b> ".$info['phone'] . "</td> "; 
}
$output.="<tr></table>";
print $output;
?>

它以长水平线显示所有结果我如何打破结果以便它们显示3 次后在新行中.

$counter = 0;
while($info = mysql_fetch_array($data)) {
   if ($counter++ % 3 == 0) {
       if ($counter > 0) {
           $output .= "</tr>";
       }
       $output .= "<tr>";
   }
   // stuff
}
if ($counter > 0) {
    $output .= "</tr>";
}

$output .= "</table>";
