fpdf-如何将数据分为3列？

如何解决fpdf-如何将数据分为3列？

我已经尝试过foreach，函数和array_chunk，但是我无法在3列中显示数据。此代码为所有三列打印相同的日期。我有完整的报告PDF，但是此页面需要分成3个数组并打印。我删除了所有示例代码，因为它们都不起作用。谢谢您的指导。

<?php 
require ('conn.php');
require ('lib/fpdf.php'); 

// account or item_code for practice -- will be getting from a GET statment 
$item_code= 9999;
// query to get fields for top part of form
$info=mysqli_query($conn,"SELECT * FROM practice WHERE item_code = $item_code");
while($row=mysqli_fetch_array($info)){
  $firstname = $row['firstname'];
  $lastname = $row['lastname']; 
  $street = $row['street'];
  $city = $row['city'];
  $st = $row['st'];
  $zip = $row['zip'];
  $name = "{$row['lastname']},{$row['firstname']} ";
  $csz = "{$row['city']},{$row['st']} {$row['zip']}";
}

class PDF extends FPDF
{
  // Page header
  function Header()
  {
    // Logo
    // $this->Image('sample.png',10,6,30);

    $this->SetFont('Arial','B',15);
