เราไม่สามารถใส่ function ใน <? require('fpdf.php'); function xxx ?> ได้เหรอครับ

<?
function Header_GreenLeaf($Batch_No)
 { // start Header_GreenLeaf()
   global $Batch_No,$Drug_No,$Batch_ID,$Drug_Name,$Product_Status;
   global $Curr_Date,$Rec_Date,$Control,$Mfg_Date,$Exp_Date,$Manufac,$Amount;
   global $Batch_Size,$Reg_No,$Receive_No,$Remark;
   global $Released_Date;
   global  $NameStatus;
   global $Retest_Date;
   global $Label_Exp;

   $Curr_Date=date("Y-m-d");
  
  check_BatchNo($Batch_No);

  $sql = "SELECT * FROM batch as b ";
  $sql .= "WHERE (Batch_No='$Batch_No') ";

  $res = mysql_query($sql) or die(mysql_error());
  $nrow = mysql_num_rows($res);
 }



require('fpdf.php');

	$pdf=new FPDF();
	$pdf->AddPage();
	$pdf->AddFont('TH Niramit AS','','TH Niramit AS.php');
	$pdf->SetFont('TH Niramit AS','',15);

	FindHeadReport ($Batch_No,&$ResultLast);
	if($ResultLast=="Passed") 
	{ $pdf->Cell(0,10,'APPROVED',0,1,"C"); }
	else
	{ $pdf->Cell(0,10,'REJECTED',0,1,"C"); }
	$pdf->Cell(0,10,'Hello',0,1,"C");
	$pdf->Cell(0,10,'Finished Product',0,1,"C");
	$pdf->Cell(0,10,iconv( 'UTF-8','TIS-620','สวัสดี'),0,1,"C");
	$pdf->Cell(0,10,iconv( 'UTF-8','TIS-620','Product Name : สวัสดี '),0,1,"C");
	$pdf->Cell(0,10,iconv( 'UTF-8','TIS-620',''),0,1,"C");
	$pdf->Output("MyPDF/MyPDF.pdf","F");




//$pdf->Cell(-50,10,$Drug_Name,0,1,"C");
$pdf->Output("MyPDF/MyPDF.pdf","F");
