Question

这是我的第一页，其名称为ex.php，当在ex.php上运行时，输出pdf并且pdf表相互覆盖。如何解决这个问题，请帮助我，高级谢谢

<?php
require('mysql_table.php');

class PDF extends PDF_MySQL_Table
{
function Header()
{
    //Title
    $this->SetFont('Arial','',18);
    $this->Cell(0,6,'World populations',0,1,'C');
    $this->Ln(10);
    //Ensure table header is output
    parent::Header();
}
}

//Connect to database
mysql_connect('localhost','root','');
mysql_select_db('pro');

$pdf=new PDF();
$pdf->AddPage();
//First table: put all columns automatically
$pdf->Table('select * from products');
$pdf->AddPage();
//Second table: specify 3 columns
$pdf->AddCol('Name',20,'','C');
$pdf->AddCol('Price',40,'','C');
//$pdf->AddCol('pop',40,'Pop (2001)','R');
$prop=array('HeaderColor'=>array(255,150),
            'color1'=>array(210,245),
            'color2'=>array(255,255),
            'padding'=>2);
$pdf->Table('select Name, Price from products');
$pdf->Output();
?>

这是另一个名为mysql_table.php的页面
