I’m doing this to find number of pages in a pdf. But for one pdf the pages are 20 but it’s showing 21. For rest it’s showing exact pages. I’ve checked document doesn’t seem any issue with document itself.

`function countt($url)
if ($url){
$pdf = file_get_contents($url);

            if ($pdf === false) {
                // Handle any errors when fetching the PDF
                return -1;
            }

            // Debugging: Print PDF content
            // echo $pdf;

            if ($pdf){
            $numberr = preg_match_all("//PageW/", $pdf, $dummy);

            return $numberr;
            }
        }
        }
