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.
