FPDF 在不应该的地方添加页面 -PHP

Question

我有使用 FPDF 教程制作的代码

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


class PDF extends FPDF
{
    function Header()
    {
        //cabecera de la pagina
        //lgo
        $this->Image('simpca.png',10,10,25);
        //fuente
        $this->SetFont('Arial','B',15);
        //Movemos a la derecha
        $this->Cell(80);
        //Titulo
        $this->Cell(30,10,utf8_decode('Comprobante de impuesto sobre la renta'));
        //Salto de linea
        $this->Ln(20);

        //fuente
        $this->SetFont('Arial','B',10);
        $this->Cell(0,10,utf8_decode('Carrera el saman, zona idustrial matanzas, puerto ordaz'),0,'L');

        $this->Cell(0,10,utf8_decode('Usuario: XXXXXXXXXXXXXXXXX'),0,'L');
        $fecha=date("d-m-Y");
        $this->Ln(04);
        $this->Cell(0,10,utf8_decode('Fecha: ').$fecha,0,'L');

        $this->Ln(06);
        $this->Cell(0,10,utf8_decode('RETENCIONES DE ISLR'),0,0,'C');
    }

?>

它添加一切正常，但它看起来像是在让 FPDF 添加一个新页面，所以在 $result 中我有超过 1 个项目，并且它添加了一个完整的页面（带有页眉和页脚) 对于我拥有的每一件物品。

是的，因为你的条件是作业。

 if ($i = 25 || $i = 0)

应该是

if ($i == 25 || $i == 0)
