 我使用此代码生成PDF并打印出来。 然后我意识到页面大小不适合A4。

答

The problem is that you pass the wrong default page size (595.28mm by 841.89mm) to the FPDF constructor, which by the way should be FDPF. A4 is 210mm by 297mm if in portrait mode.

So you should call the constructor this way:

$pdf = new FPDF('P','mm','A4');

$pdf = new FPDF('P','mm',array(210,297));

After that you can omit the page size parameter when calling AddPage().

Here is a complete Hello World example:

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

$pdf = new FPDF('P','mm','A4');
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
