"MsDoc" reader fails to open and/or correctly process MS Word 97-2003 (*.doc) files

[voltel]

This is:

• a bug report

Expected Behavior

1. The MS Word 97-2003 document (*.doc) would be correctly opened and correctly processed by
   $phpWord = IOFactory::load($c_file_name, 'MsDoc'); // this line causes error

2. styles would be internally set in MsDoc.php in generatePhpWord() method:

        foreach ($this->arraySections as $itmSection) {
            $oSection = $this->phpWord->addSection();
            $oSection->setStyle($itmSection->styleSection); // this line causes error
        ...

Current Behavior

Errors, inconsistently different:

Notice: Uninitialized string offset: 327680 (or some other wildly large number)
Error traced in getInt2d() and/or getInt1d() of vendor\phpoffice\phpword\src\PhpWord\Reader\MsDoc.php (line 2317)

or

Fatal error: Uncaught PhpOffice\PhpWord\Exception\Exception: Could not open resources/resources/n_466.doc for reading! File does not exist, or it is not readable. in D:\xxx\xxx\vendor\phpoffice\phpword\src\PhpWord\Shared\OLERead.php:78

or

Notice: Undefined property: stdClass::$styleSection
traced to vendor\phpoffice\phpword\src\PhpWord\Reader\MsDoc.php generatePhpWord()

or, when it manages to convert some test file, the layout is completely wrong:
no styles, line breaks in wrong places, parts of words are missing, table is not reproduced.

the elements recognized by the following snippet are of type Text, with failed recognition of paragraphs. A simple table has not been recognized at all.

Failure Information

I tried all possible versions of MS Word 97-2003 documents (created from MS Word 2007, or in MS Word 365). I tried to process downloaded files (i.e. from here n_466.doc or d466.doc), or I created new files manually in both available to me versions of MS Word (2007 and 365) and saved them as *.doc.
The provided set-up (see further) works OK with the same documents saved as .docx files (different reader class).
test_documents.zip

Version, copied from the composer.json:
"phpoffice/phpword": "^0.14.0",

or form composer.lock:
"name": "phpoffice/phpword",
"version": "v0.14.0",
"source": {
"type": "git",
"url": "https://github.com/PHPOffice/PHPWord.git",

Hey @Progi1984 , any luck with this? I am seeing similar behavior. It seems unable to read a pretty standard Word97 doc, no special formatting. Instead I get broken, fragmented text and/or not getting other sections entirely.

I was able to get much better results from a simple fread style function. But that was only useful for plaintext extraction, no style or formatting data unfortunately.

function readWord($filename) {
        if(file_exists($filename))
        {
            if(($fh = fopen($filename, 'r')) !== false )
            {
                $headers = fread($fh, 0xA00);

                // 1 = (ord(n)*1) ; Document has from 0 to 255 characters
                $n1 = ( ord($headers[0x21C]) - 1 );

                // 1 = ((ord(n)-8)*256) ; Document has from 256 to 63743 characters
                $n2 = ( ( ord($headers[0x21D]) - 8 ) * 256 );

                // 1 = ((ord(n)*256)*256) ; Document has from 63744 to 16775423 characters
                $n3 = ( ( ord($headers[0x21E]) * 256 ) * 256 );

                // 1 = (((ord(n)*256)*256)*256) ; Document has from 16775424 to 4294965504 characters
                $n4 = ( ( ( ord($headers[0x21F]) * 256 ) * 256 ) * 256 );

                // Total length of text in the document
                $textLength = ($n1 + $n2 + $n3 + $n4);

                $extracted_plaintext = fread($fh, $textLength);

                return $extracted_plaintext;
            } else {
                return false;
            }
        } else {
            return false;
        }
    }

Any updates on this? Trying to convert a .doc file to pdf, it works, but in the pdf part of the text is cut off and the italics are gone.

`
require 'vendor/autoload.php';

use PhpOffice\PhpWord\IOFactory;
use PhpOffice\PhpWord\Settings;

Settings::setPdfRendererName(Settings::PDF_RENDERER_DOMPDF);
Settings::setPdfRendererPath('.');

$phpWord = IOFactory::load('TEST2.doc', 'MsDoc');
$phpWord->save('word_doc.pdf', 'PDF');
