我正在使用FPDF创建PDF报告.现在,如何在页面底部的报表的每个页面上生成页码.
以下是生成2页PDF的示例代码.

<?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();


        ?>

注意：$j值将来自数据库,因此我们不知道报告将有多少页面.

$pdf->AddPage("P","A4");

class PDF extends FPDF
{
    function Footer()
    {
        // Go to 1.5 cm from bottom
        $this->SetY(-15);
        // Select Arial ITalic 8
        $this->SetFont('Arial','I',8);
        // PRint centered page number
        $this->Cell(0,10,'Page '.$this->PageNo(),'C');
    }
}
