使用PHP获取PDF文件中的字段 [英] Get fields in a PDF file using PHP
问题描述
如何使用PHP找出PDF文件中的字段名称?
How can I find out the name of the fields in a PDF file using PHP?
我唯一想到的就是将PDF文件转换为HTML,但这听起来实在是太过分了.
The only thing I can think of is converting the PDF file to HTML, but that really sounds like overkill.
我的最终目标是生成一个FDF文件(对此我很满意)来填充我无法控制的PDF文件的字段,因此我不知道我需要使用哪些字段名称使用.
My end goal is to generate an FDF file (this bit I'm happy with) to populate the fields of a PDF file which I don't have control over, so I don't know what field names I need to use.

pdftk命令可以从PDF表单文件生成FDF文件.
The pdftk command can generate an FDF file from a PDF form file.
pdftk formfile.pdf generate_fdf
pdftk formfile.pdf generate_fdf
form字段是输出中看起来像的部分
The form fields are the portion of the output that looks like
...
<< /T(f1-1) /V(text of field) >>
<< /T(f1-2) /V(text of another field) >>
...
