Database Details in PDF are not getting filled? - php

Question

I am extracting data from MySQL database using php and exporting it as PDF. The columns are not getting filled due to the PDF page size. How do I push the unfilled columns to next line? So that first line has 4 columns and next line has another 4 columns, so on..
<?php
//include connection file
include_once "connection.php";
include_once 'fpdf/fpdf.php';
class PDF extends FPDF {
// Page header
function Header() {
}
// Page footer
function Footer() {
// Position at 1.5 cm from bottom
$this->SetY(-15);
// Arial italic 8
$this->SetFont('Arial', 'I', 8);
// Page number
$this->Cell(0, 10, 'Page '.$this->PageNo().'/{nb}', 0, 0, 'C');
}
}
$db = new dbObj();
$connString = $db->getConnstring();
$id = $_GET['id'];
$query = $connString->prepare("SELECT ID, Name, Wrongs, Rights, Percentage, Age FROM Datas WHERE ID=?");
$query->bind_param('s', $id);
$query->execute();
$result = $query->get_result();
$display_heading = array('ID' => 'ID', 'Name' => 'Name', 'Wrongs' => 'Wrongs', 'Rights' => 'Rights', 'Percentage' => 'Percentage', 'Age' => 'Age');
//$result = mysqli_query($connString, "SELECT ID, Name, Wrongs, Rights, Percentage, Age FROM Datas") or die("database error:". mysqli_error($connString));
$header = mysqli_query($connString, "SHOW columns FROM Datas");
$pdf = new PDF();
//header
$pdf->AddPage();
//foter page
$pdf->AliasNbPages();
$pdf->SetFont('Arial', 'B', 12);
foreach ($header as $heading) {
$pdf->Cell(45, 12, $display_heading[$heading['Field']], 1);
}
foreach ($result as $row) {
$pdf->Ln();
foreach ($row as $column) {
$pdf->Cell(45, 12, $column, 1);
}
}
$pdf->Output();
