在使用php打印每個pdf頁面后，如何增加pdf中的收據編號？

Question

我需要在打印每個pdf后通過遞增顯示收據編號，我正在使用fpdf創建收據，我想計算第一頁第一頁，第二頁第二頁的收據編號，依此類推。

我可以為此使用會話嗎？

任何幫助表示贊賞。

這是我的pdf代碼：

<?php
    if(!empty($_POST['register']))
    {
        $calender=$_POST['datum1'];
        $time=$_POST['timepicker_6'];
        $respected=$_POST['first_name'];
        $month=$_POST['second_name'];
        $year=$_POST['third_name'];
        $fees=$_POST['fourth_name'];
        $amount=$_POST['fifth_name'];
    require("fpdf/fpdf.php");

    $pdf=new FPDF();
    $pdf->Addpage();
    // Logo
    $pdf->Image('33990.jpg',10,2,30);
    $pdf->SetFont("Arial","B",20);
    $pdf->cell(0,10,"Madirasheri Mahal Jamath ",0,1,'C');
    $pdf->SetFont("Arial","B",18);
    $pdf->cell(0,10,"P.O Thrikanapuram-679573,register number:529/98 ",0,1,'C');

    $pdf->SetFont("Arial","B",18);
    $pdf->Cell(0,10,"Receipt number:",0,0,'C');

    $pdf->SetFont("Arial","B",18);
    $pdf->cell(0,10,"Date:{$calender} ",0,1,'R');  


    $pdf->cell(0,10,"Time:{$time}",0,1,'R');


    $pdf->cell(0,30,"We have received sum of Rs  {$fees},for the month of ",0,1);

    $pdf->cell(0,-15,"{$month},{$year} From Mr/Mrs {$respected}.",0,1);

    $pdf->cell(0,60,"Amount :{$amount} ",0,1);
    $pdf->cell(0,20,"Secretory: ........... ",0,1,'R');

    $pdf->output();
    }
?>

FPDF帶有一個稱為PageNo的內置函數，該函數PageNo您的需要。

$pdf->Cell(0,10,"Receipt number: ".$pdf->PageNo(),0,0,'C');
