$pdf->SetXY(40, 0); // Doesn't work
$pdf->Write(0, 'This is just a simple text'); // Doesn't work
$pdf->Output(); // Doesn't work

推荐答案

Laravel无法没有内置方式来编辑PDF .您当然可以将外部库(例如 FPDF )与 PDFlib 能够编辑PDF.

There is no built-in way for Laravel to edit PDFs. You can of course use external libs, such as FPDF with the FPDI extension to modify PDFs - the result is a new PDF file. There is also a paid lib PDFlib that is capable of editing PDFs.

要在Laravel中安装FPDF + FPDI，只需运行:

To install FPDF + FPDI in Laravel you just need to run:

composer require setasign/fpdf && composer require setasign/fpdi

这将安装基本的FPDF库+扩展名FPDI.然后，您可以创建一个新实例并使用以下命令编辑PDF:

This will install the base FPDF lib + the extension FPDI. Afterwards you can create a new instance and edit your PDF with:

$pdf = new \FPDI();
$pdf->setSourceFile('PATH/TO/SOURCEFILE');

请熟悉 FPDI文档

更新: 使用FPDI，您不能直接编辑PDF文件. FPDI所做的一切都是从给定的PDF文件中提取内容为可重用的格式-结果是一个完整的新PDF.此信息也可以在常见问题解答.

Update: With FPDI you cannot directly edit a PDF file. All FPDI does is extracting content from a given PDF file into a reusable format - the result is a complete new PDF. This information can also be found in the FAQ of FPDI.
