Count pages in PDF file using Imagemagick - PHP

Question

I am using PHP 5 with Apache in my Windows Vista PC. I have Imagemagick already installed and configured. I want to count the total number of pages in a pdf file using imagick.

I fount one solution here, but dont know how to open pdf file as text and count pages.

somebody give me a clear solution to count pages using imagemagick like

identify -format %n testfile.pdf

From googling, I found some workarounds or examples;

1. imagick(identify -format %n testfile.pdf)
2. identify -density 12 -format "%p" testfile.pdf
3. identify -format %n testfile.pdf

I don't know how to make use of this stuff..

Answer 1

Instead of using "identify -format %n $file"(which can turn out to be extremely slow for complex or for mult-page PDFs) you should rather use the right tool for the job, pdfinfo:

exec("pdfinfo $file | grep Pages: | awk '{print $2}'")

which is faster by several magnitudes...

Answer 2

I solved it using;

exec("identify -format %n $file")
