This article illustrates how PHP simply reads PDF pages. Share to everyone for your reference, specific as follows:

Or foreigners more honest, in the foreigner's website found such a way,

I wrote a function to write the function into the Pdfutil class in my Leelib library.

In a very simple way, the speed is good.

/**
* Get PDF pages *
/
function Getpagetotal ($path) {
    //Open File
    if (! $fp = @fopen ($path, "R")) {
      $ Error = "Open file {$path} failed";
      return false;
    }
    else {
      $max =0;
      while (!feof ($fp)) {
        $line = fgets ($fp, 255);
        if (Preg_match ('/\/count [0-9]+/', $line, $matches)) {
          preg_match ('/[0-9]+/', $matches [0], $matches 2);
          if ($max < $matches 2[0]) $max = $matches 2[0];
        }
      Fclose ($FP);
      Returns the number of pages return
      $max;
    }
}
