As far as I remember you can't do it with vanilla FPDF. You can either extend it to have a method that would return this value for you, or just store the width as a public property of fpdf object.
据我记得你不能用香草 FPDF 做到这一点。您可以将其扩展为具有为您返回此值的方法，也可以将宽度存储为 fpdf 对象的公共属性。

Needed to do this myself so was just checking the most recent version of FPDF and it looks like the width & height are already available as public properties. So for anyone looking for the same info:
需要自己做这件事，所以只是检查最新版本的 FPDF，看起来宽度和高度已经作为公共属性可用。所以对于任何寻找相同信息的人：
$pdf = new FPDF();
$pdf->addPage("P", "A4");
$pdf -> w; // Width of Current Page
$pdf -> h; // Height of Current Page
$pdf -> Line(0, 0, $pdf -> w, $pdf -> h);
$pdf -> Line($pdf -> w, 0, 0, $pdf -> h);
$pdf->Output('mypdf.pdf', 'I');

Nowadasy, you can simply call GetPageWidthand GetPageHeightmethods.
现在，您可以简单地调用GetPageWidth和GetPageHeight方法。
$pdf = new FPDF();
$pdf->addPage("P", "A4");
$pdf->GetPageWidth(); // Width of Current Page
$pdf->GetPageHeight(); // Height of Current Page

Encase someone needs to get the width taking margins into consideration...
包住某人需要考虑到边距的宽度......
class FPDF_EXTEND extends FPDF
{
public function pageWidth()
{
$width = $this->w;
$leftMargin = $this->lMargin;
$rightMargin = $this->rMargin;
return $width-$rightMargin-$leftMargin;
}
}
