Count the number of pages in a PDF in only PHP [closed]

Question

I need a way to count the number of pages of a PDF in PHP. I've done a bit of Googling and the only things I've found either utilize shell/bash scripts, perl, or other languages, but I need something in native PHP. Are there any libraries or examples of how to do this?

Answer 1

If using Linux, this is much faster than using identify to get the page count (especially with a high number of pages):

exec('/usr/bin/pdfinfo '.$tmpfname.' | awk \'/Pages/ {print $2}\'', $output); 

You do need pdfinfo installed.

Answer 2

I know this is pretty old... but if it's relevant to me now, it can be relevant to others too.

I just worked out this method of getting page numbers, as the methods listed here are inefficient and extremely slow for large PDFs.

$im = new Imagick(); $im->pingImage('name_of_pdf_file.pdf'); echo $im->getNumberImages(); 

Seems to be working great for me!
