You can't get meaningful metadata with PHP in windows for many applications. The only real exception for this would be using PHP's Component Object Model.

Here is an example for word / excel:

// for MSExcel use:
$objOfficeApp = new COM("excel.application") or die("unable to instantiate MSExcel");
// for MSWord use:
//$objOfficeApp = new COM("word.application") or die("unable to instantiate MSWord");

$objOfficeApp->Workbooks->Open( "c:\\temp\\test.xls" );
//$objOfficeApp->Documents->Open( "c:\\temp\\test.doc" );

$objDocProps = $objOfficeApp->ActiveWorkBook->BuiltInDocumentProperties();
//$objDocProps = $objOfficeApp->ActiveDocument->BuiltInDocumentProperties();

$count = $objDocProps->count();

while( $objDocProp = $objDocProps->Next() ) {
    print $objDocProp->Name() . ': ' . $objDocProp->Value() . "\n";
}

unset($objDocProp);
unset($objDocProps);

$objOfficeApp->ActiveWorkBook->Close();
//$objOfficeApp->ActiveDocument->Close();
$objOfficeApp->Quit();
unset($objOfficeApp);
