问题
For the longest time now I've been trying to convert HTML pages containing large tables to PHP. These are styled with CSS and can be several pages long.
I first tried DOMPDF. It works great, until a document is more than one page. None of the fixes I've found work. Either it errors out, or any element that would be even partially on the second page gets lumped over the content of page 1. I've tried both the latest release and the SVN copy I checked out today.
I also tried html2ps/pdf, and it gives me "permission denied" errors writing to the cache directory, even though the directory is fully writable. The system requirements test script passes. The server is running PHP 5 under IIS (not my choice heh).
Can either of these be convinced to work, or is there a library that can do it?
Errors from the demo/test scripts:

回答1:
A similar problem with html2pdf under IIS has been discussed here.
The solution was quite simple, yet weird. If this doesn't help you, a full error-message and / or a little bit of code would help me to help you.
回答2:
I personally recommend command line applications instead of any PHP libraries.
Reasons :
PHP libraries need more time and memory (cache) for conversion process.
They need well-formatted HTML pages only, otherwise throw errors or warnings.
No support for external style sheets.
Command Line Tool:
If you run your script on a Linux server then I suggest command line tools.
Reasons :
They are extremely fast compared to PHP libraries.
Support CSS.
Accept non-well-formatted HTML.
Which command line tool to use?
- wkhtmltopdf
- htmltopdf
- html2pdf
For more information refer to Converting HTML to PDF (not PDF to HTML) using PHP.
