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..

Solution 1

I solved it using;

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

Solution 2

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...

This will be extremely slow for multi-page PDFs, especially for ones with more complex graphics on the pages...

Useful pointer, but I had some difficulty figuring out how to get pdfinfo in my systems. Finally: Debian/Ubuntu: sudo aptitude install poppler-utils; OSX: brew install poppler.

This solution will work not in all cases. For me this script didn't work for PDF 1.6, but worked for 1.4 and 1.5 versions

the PDFlib library no longer maintained since 2010. But even worst, its commercial and not public domain.
