How to get text position in PDF using PHP, TCPDF & FPDI?

Question

I have an issue: I need to upload some PDF template with data and then change it. For example, in PDF file is string:

NAME:

I need get position of this string and insert some text (username etc.) after it.

Is it possible ?

Update

The PDF isn't encrypted. Text is embedded as text.

Answer 1

如果未加密PDF（没有主密码/客户密码），并且文本作为文本而不是作为渲染的图像嵌入，则可以对它进行一些基本的字符串搜索/替换-PDF本质上是Postscript代码，并且您可以将其大部分视为纯文本。

Answer 2

This is not trivial and not possible with 100% reliability inside a PDF file because you may have to re-render the layout (to accommodate for elements moving, lines breaking etc.)

If you need to change some static form fields, you may be able to work with simple search+replace operations. For anything more complex, see eg this question of mine for some background and possible solutions: PHP PDF template library with PDF output?
