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:

[code=php]
<?php
$filename = "file.php";
$num = count(file($fil ename));
echo $num;
?>
[/code]

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!
