Utilizzando questo codice

define('FPDF_FONTPATH','/font/');
require('fpdf.php');
class PDF extends FPDF
{
//Simple table
function BasicTable($header,$data)
{
    //Header
    foreach($header as $col)
        $this->Cell(40,7,$col,1);
    $this->Ln();
    //Data
    foreach($data as $row)
    {
        foreach($row as $col)
            $this->Cell(40,6,$col,1);
        $this->Ln();
    }
}
}
$query = "SELECT * FROM log_visite";
$result = mysql_query($query);
$result = mysql_query($query);
while($row = mysql_fetch_assoc($result)){
  $array[] = $row;
$data = $array;}
$pdf = new PDF();
$header=array('ID','Browser e SO','IP','Errore','Data','Ora','Provenienza','Nazione');
$pdf->AddPage();
$pdf->BasicTable($header,$data);
$pdf->Output();
    }
