You can find the number of pages in a PDF document by using the following code, using PHP4:

        //where $file is the full path to your PDF document.
        if(file_exists($file)) {
                        //open the file for reading
            if($handle = @fopen($file, "rb")) {
                $count = 0;
                $i=0;
                while (!feof($handle)) {
                    if($i > 0) {
                        $contents .= fread($handle,8152);
                    }
                    else {
                          $contents = fread($handle, 1000);
                        //In some pdf files, there is an N tag containing the number of
                        //of pages. This doesn't seem to be a result of the PDF version.
                        //Saves reading the whole file.
                        if(preg_match("/\/N\s+([0-9]+)/", $contents, $found)) {
                            return $found[1];
                        }
                    }
                    $i++;
                }
                fclose($handle);
 
                //get all the trees with 'pages' and 'count'. the biggest number
                //is the total number of pages, if we couldn't find the /N switch above.                
                if(preg_match_all("/\/Type\s*\/Pages\s*.*\s*\/Count\s+([0-9]+)/", $contents, $capture, PREG_SET_ORDER)) {
                    foreach($capture as $c) {
                        if($c[1] > $count)
                            $count = $c[1];
                    }
                    return $count;            
                }
            }
        }
        return 0;
 
 

it has worked with all the PDF docs i've used it with so far, irrelevant of PDF version. I imagine a similar approach could be used for at least .DOC files though i haven't tested that out.

for txt and probably doc you can use:

<?php
$filename = "file.php";
$num = count(file($filename));
echo $num; 
?>

Hi coffeemist,

I tested your code. It works some of the pdf files, but it doesn't work for the pdf files that contain all the images. It returns page count 0. I need to determine page count in user uploaded pdf files either in php or perl. Any help will be greatly appreciated.

Thank you very much!
