Created a PDF file that displays strange characters

This is my code that will receive data from the database, then save it in a table for the .pdf file:

<?php

// test the table functions
error_reporting(E_ALL);
include('includes/pdf/class.ezpdf.php');
  //echo 'AAA-1-';
  $pdf = new Cezpdf();
  //$pdf->selectFont('./fonts/Helvetica');

  //connect to db
  session_start();
  require_once('connect/ticketivity_connect.php');
  //echo 'AAA-2-';


  //get customer details
  $sql_cust = "SELECT * FROM customers where customer_id = '".$_GET['customerid']."'";
  $res_cust = mysql_query($sql_cust);
  $num_cust = mysql_num_rows($res_cust);
  $row_cust = mysql_fetch_assoc($res_cust);

  //display customer details
  $db_data[] = array('first' => 'Customer Name:', 'second' => $row_cust['cust_name']);
  $db_data[] = array('first' => 'Phone Number:', 'second' => $row_cust['cust_phone']);
  $db_data[] = array('first' => 'Address:', 'second' => $row_cust['cust_address']);
  $db_data[] = array('first' => '>Customer Ref/ Room Number:', 'second' => $row_cust['cust_ref']);
  //echo 'AAA-3-';
  //get order
  $sql_orderinfo= "SELECT * FROM orders where customer_id = '".$_GET['customerid']."'";
  $res_orderinfo = mysql_query($sql_orderinfo);
  $num_orderid = mysql_num_rows($res_orderinfo);
  $row_orderid = mysql_fetch_assoc($res_orderinfo); 
  //echo 'AAA-4-';
  //display order id
  $orderid_len = strlen($row_orderid['order_id']);
  if($orderid_len == 1) { 
   //echo 'AAA1--';
   $db_data[] = array('first' => 'Order ID:', 'second' => '00000'.$row_orderid['order_id']);
  } else if ($orderid_len == 2){ 
   //echo 'AAA2--';
   $db_data[] = array('first' => 'Order ID:', 'second' => '0000'.$row_orderid['order_id']);
  } else if ($orderid_len == 3){ 
   //echo 'AAA3--';
   $db_data[] = array('first' => 'Order ID:', 'second' => '000'.$row_orderid['order_id']);
  } else if ($orderid_len == 4){
   //echo 'AAA4--';
   $db_data[] = array('first' => 'Order ID:', 'second' => '00'.$row_orderid['order_id']);
  } else if ($orderid_len == 5){ 
   //echo 'AAA5--';
   $db_data[] = array('first' => 'Order ID:', 'second' => '0'.$row_orderid['order_id']);
  } else if ($orderid_len == 6){
   //echo 'AAA6--';
   $db_data[] = array('first' => 'Order ID:', 'second' => $row_orderid['order_id']);
  } 

  //table columns
  $col_names = array(
   'first' => 'first',
   'second' => 'second',
  );
  //echo 'AAA-5-';
  $table_title = 'Customer Details';
  //echo 'AAA-6-';
  $pdf->ezTable($db_data, $col_names, $table_title, array('width'=>550));
  if (isset($d) && $d){
   //echo 'AAA-if';
   $pdfcode = $pdf->output(1);
   $pdfcode = str_replace("\n","\n<br>", $pdfcode);
   echo '<html><body>';
   echo trim($pdfcode);
   echo '</body></html>';
  } else {
   //echo 'AAA-else';
   $pdf->ezStream();
  }

?>

The question is not very clear, but I assume that you are writing a web application and you are trying to transfer a PDF document to a client.

First you need to set the header so that the client knows that he should expect PDF data:

header('Content-type: application/pdf');

This will force most browsers to display PDF in the browser window. If you prefer the browser to offer PDF as a download, do this in addition to the above:

header('Content-Disposition: attachment; filename="filename.pdf"');

You can set any file name you like instead filename.pdf.

, header() , .

, , $d , , , . , PDF.
