Getting PDF information in PHP

[barron]

I have a project that will need me to know the page size of a PDF and the page count. Is there a way that avoid PDFLib_PDI doing this? I know I can read the whole PDF and then get that, but that seems like a lot of trouble for two, minor bits of information.

Thanks

i havnt looked at the source code for much of PDFLib so I dont know how they implement obtaining info on a document, but the way pdf's are written is so you can essentially load thousands of pdf pages with limited memory. they are complicated documents with tree structures and roots containing information. a header in a pdf will contain a bunch of information on the document, including the number of pages, however page size isnt included. you may be best to stick with pdflib or the similar but free, fpdf unless you want to write a potentially complex app in php to open the document and parse the binary data down. the acrobat 1.6 spec itself is 1216 pages, of course it contains everything, and you are only looking for two pieces of info. just some thoughts though.

Thanks,

I realized that page size is a per page, not per document parameter, so it can't be one size fits all. But I like the page count idea. I'll probably have to just load one page of the PDF and measure it with FPDF or PDFLib.
