$mypdf->Open();
$mypdf->AddPage();
$mypdf->SetFont('Arial','B',16);
$mypdf->Cell(40,10,'Vasanthanpv@gmail.com');


$dir='C:/xampp/htdocs/test/';
$filename= "vasanthan.pdf";
$mypdf ->Output($dir.$filename)

?>

<?php

define('FPDF_FONTPATH','font/');

require('fpdf.php');

$mypdf=new FPDF();

$mypdf->Open();

$mypdf->AddPage();

$mypdf->SetFont('Arial','B',16);

$mypdf->Cell(40,10,'Vasanthanpv@gmail.com');

$dir='C:/xampp/htdocs/test/';
