FPDI-2.3.6“致命错误：未捕获的错误：未找到“FPDI”类”(2021)

Question

我下载并解压缩FPDF 1.83和FPDI 2.3.6，在我正确加载后：

<?php
require_once('fpdf183/fpdf.php');
require_once('FPDI-2.3.6/src/autoload.php');

但是当我尝试使用时：

<?php
require_once('fpdf183/fpdf.php');
require_once('FPDI-2.3.6/src/autoload.php');

$pdf = new FPDI();

Fatal error: Uncaught Error: Class "FPDI" not found ... on line 5

我该如何解决这个问题？如何在不使用 composer 的情况下使用所有功能 FPDI 和 FPDF ？

Answer 1

您需要使用附加行：use setasign\Fpdi\Fpdi;

<?php
require_once('fpdf183/fpdf.php');
require_once('FPDI-2.3.6/src/autoload.php');
use setasign\Fpdi\Fpdi;

但是，在2021 中使用 PDFI 打开 PDF 可能会得到：

Alternatively the document you're trying to import has to be resaved without the use of compressed cross-reference streams and objects by an external programm (e.g. by lowering the PDF version to 1.4).

然后setasign.com回复：We offer a commercial addon which enables FPDI to handle documents that uses these compression features.:@
