I am creating PDF reports using FPDF. Now how do I generate page numbers on each page of a report at the bottom of the page. Below is the sample code for generating a 2 page PDF.

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

        $pdf = new FPDF();
        $pdf->AliasNbPages();
        $pdf->AddPage();
        $pdf->SetFont('Arial','',16);

        $start_x=$pdf->GetX(); 
        $current_y = $pdf->GetY();
        $current_x = $pdf->GetX();

        $cell_width = 25; $cell_height=14; 
        $j = 20;  // This value will be coming from Database so we dont know how many pages the report is going to be 
        for ($i = 0; $i<$j ; $i++){
            $pdf->MultiCell($cell_width,$cell_height,'Hello1',1);
            $current_x+=$cell_width;
            $pdf->Ln();
        }

        $pdf->Output();


        ?>

Note : The $j value will be coming from the database so we don't know how many pages is the report going to be.

According to my comment you can place

$pdf->PageNo();

on your page where ever you like. Also you can add a placeholder to this

$pdf->AliasNbPages(); 

What would look like

$pdf->AliasNbPages('{totalPages}');

By default it's {nb}. It's not necessary to add a placeholder

Than you could add the pagesum like

$pdf->Cell(0, 5, "Page " . $pdf->PageNo() . "/{totalPages}", 0, 1);

or without your own placeholder

$pdf->Cell(0, 5, "Page " . $pdf->PageNo() . "/{nb}", 0, 1);

this would produce e.g.

Page 1/10

in case there were 10 pages :)

But beware

Using the placeholder will mess up the width of the cell. So if you have e.g. 180 page-width than 90 isn't the mid anymore (In the line where you use the placeholder). You will see if you try :)
