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

Answer 1

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!
