created a PDF that outputs weird characters
This is my code which will get data from the database then store it in a table for .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开发者_StackOverflow社区--';
$db_data[] = array('first' => 'Order ID:', 'second' => '000'.$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();
}
?>

What do I need to do/add?
The question isn’t very clear, but I assume you’re writing a web application, and you’re trying to serve up the PDF document to the client.
First, you need to set a header to let the client know that it should expect PDF data:
header('Content-type: application/pdf');
That will cause most browsers to render the PDF within the browser window. If you’d rather have the browser offer the PDF as a download, do this in addition to the above:
header('Content-Disposition: attachment; filename="filename.pdf"');
You may set any filename you like in place of filename.pdf.
It’s important that you make these calls to header() before any output is written.
As an aside, I guess that $d is a debug flag, but I don’t think it’s a very good idea to do those string operations that you’re doing when it’s set. You’re likely to end up corrupting the PDF data.
