Writing/Drawing over a PDF template document in PHP
提问by filip-fku
I'd like to be able to write/overlay text over an existing pdf document using PHP. What I am hoping to do is have a pdf document that can act as a template, and fill in the gaps by opening the template doc, overlaying the relevant text, and serving the result as a new document. The template document is a single page so page merging/manipulation is not necessary.
我希望能够使用 PHP 在现有的 pdf 文档上编写/覆盖文本。我希望做的是有一个可以充当模板的pdf文档，并通过打开模板文档，覆盖相关文本并将结果作为新文档提供来填补空白。模板文档是单个页面，因此不需要页面合并/操作。
Are there any free libraries that can do this? Anywhere I should look? Most searches I've done seem to deal with merging documents/adding pages, instead of overlaying content over an existing page.
有没有可以做到这一点的免费图书馆？我应该看哪里？我所做的大多数搜索似乎都在处理合并文档/添加页面，而不是在现有页面上覆盖内容。
Thanks.
谢谢。

Here is some sample code for any future wanderers (adapted from the samples at www.setasign.de):
以下是一些适用于任何未来流浪者的示例代码（改编自 www.setasign.de 上的示例）：
<?php
include('fpdf.php');
include('fpdi.php');
// initiate FPDI
$pdf =& new FPDI();
// add a page
$pdf->AddPage();
// set the sourcefile
$pdf->setSourceFile('templatedoc.pdf');
// import page 1
$tplIdx = $pdf->importPage(1);
// use the imported page as the template
$pdf->useTemplate($tplIdx, 0, 0);
// now write some text above the imported page
$pdf->SetFont('Arial');
$pdf->SetTextColor(255,0,0);
$pdf->SetXY(25, 25);
$pdf->Write(0, "This is just a simple text");
$pdf->Output('newpdf.pdf', 'D');
?>

Have a look at the FPDI Libraryan add on to FPDFfor template annotation.
It can also bolt-on to TCPDF, another popular PHP PDF library. An existing PDF is used as the base of a page, instead of a blank, after that the procedures are the same as regular PDF creation.
它还可以附加到另一个流行的 PHP PDF 库TCPPDF。现有的 PDF 被用作页面的基础，而不是空白，之后的过程与常规 PDF 创建相同。

You probably want to use PDF Forms for what you want to do. To fill these babies you could use the FDF method described here: Using HTML forms to fill in PDF fields with PHP and FDF.
There is actually another nice SO post about PDF form filling here: Filling PDF Forms with PHP.
您可能想使用 PDF 表单来完成您想做的事情。要填充这些婴儿，您可以使用此处描述的 FDF 方法：使用 HTML 表单使用 PHP 和 FDF 填充 PDF 字段。
实际上还有另一篇关于 PDF 表单填写的好帖子：Filling PDF Forms with PHP。

When you want to use PDF lib to write over a document, positionning is time consuming and boring. Dhek is useful for such task: https://github.com/applicius/dhek/releases.
当您想使用 PDF 库来覆盖文档时，定位既费时又乏味。Dhek 对此类任务很有用：https: //github.com/applicius/dhek/releases。
JSON mapping over PDF page/coordinates is defined, so that you can write with PDF API you prefer.
定义了 PDF 页面/坐标上的 JSON 映射，以便您可以使用您喜欢的 PDF API 进行编写。
