Following the topic about generating PDF documents from within PHP has prompted a thought...
Is it possible to have PHP dynamically build an HTML page (from database data etc) and provide an option to output the page as PDF without going through all the database query routine again?
In other words, to produce a PDF file from dynamic HTML.
This is because I have seen at least one 'product' that reports to produce PDF from HTML 'files'.
Well, providing you save the generated HTML somewhere (if you just send it to the client, then you don't have a copy of it) and this "product" can be called through exec(), system(), etc, then sure it's possible. It's going to take another request to the server where you'll load the cached HTML version of the page, run it through the "product", send PDF headers and/or send the PDF file.
Can't give specific examples, but hopefully that gives you an idea.
