php - 在 TCPDF 中，如何将当前页码获取为整数？

Question

我尝试使用 $pdf-getAliasNumPage() ，如果以 PDF 格式呈现，它会显示页码。

但是当我在一个基本的 PHP 上进行试验并打印它时，它只返回“{:pnp:}”。

如果页面已经更改，我曾经有一个 if 条件，以便我可以再次重置值 = 0，但由于 getAliasNumPage() 的返回值等于 "{:pnp: }".

有什么方法可以找到整数形式的页码吗？那是什么 TCPDF 功能？

我只声明了一次 AddPage()，因为我不需要它。

已经使用了$pdf->getPage();只返回 0。

谢谢!

Answer 1

PageNo() 和 getPage() 都会返回当前页码。

$this->PageNo();

$this->getPage();
