Find out page numbers of PDF, Docx, Doc, Ppt, Pptx files with PHP

Question

I want this functionality in my PHP application:

When user upload a document (PDF, DOCX, DOC, PPT, PPTC extensions) then after uploading user get the total number of pages of document.

But without using exec() function.

Answer 1

It is possible to do some formats right in PHP. The DOCx and PPTx are easy:

For Word files:

function PageCount_DOCX($file) {
    $pageCount = 0;

    $zip = new ZipArchive();

    if($zip->open($file) === true) {
        if(($index = $zip->locateName('docProps/app.xml')) !== false)  {
            $data = $zip->getFromIndex($index);
            $zip->close();
            $xml = new SimpleXMLElement($data);
            $pageCount = $xml->Pages;
        }
        $zip->close();
    }

    return $pageCount;
}

and for PowerPoint

function PageCount_PPTX($file) {
    $pageCount = 0;

    $zip = new ZipArchive();

    if($zip->open($file) === true) {
        if(($index = $zip->locateName('docProps/app.xml')) !== false)  {
            $data = $zip->getFromIndex($index);
            $zip->close();
            $xml = new SimpleXMLElement($data);
            print_r($xml);
            $pageCount = $xml->Slides;
        }
        $zip->close();
    }

    return $pageCount;
}

Older Office documents are a different story. You'll find some discussion about doing that here: How to get the number of pages in a Word Document on linux?

As for PDF files, I prefer to use FPDI, even though it requires a license to parse newer PDF file formats. You can use do it simply like this:

function PageCount_PDF($file) {
    $pageCount = 0;
    if (file_exists($file)) {
        require_once('fpdf/fpdf.php');
        require_once('fpdi/fpdi.php');
        $pdf = new FPDI();                              // initiate FPDI
        $pageCount = $pdf->setSourceFile($file);        // get the page count
    }
    return $pageCount;
}
