PHP xls, xlsx, ppt, pptx headers

Here is my code where I am trying to send a correct header depedning on a type of a document. I figured out the headers for pdf, doc and docx but I still need to know correct header for Excel and Powerpoint files.

Any help appreciated.

    $document = urldecode($_GET['document']);
    $extension = end(explode('.', $document));
    $mimeType = '';
    switch ($extension) {
        case 'pdf':
            $mimeType = 'pdf';
            break;
        case 'doc':
            $mimeType = 'msword';
            break;
        case 'docx':
            $mimeType = 'msword';
            break;
        case 'xls':
            $mimeType = '';
            break;
        case 'xlsx':
            $mimeType = '';
            break;
        case 'ppt':
            $mimeType = '';
            break;
        case 'pptx':
            $mimeType = '';
            break;
    }       
    header('Content-type: application/' . $mimeType);

.xls

application/vnd.ms-excel

.xlsx

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

.ppt

application/vnd.ms-powerpoint

.pptx

application/vnd.openxmlformats-officedocument.presentationml.presentation

And one of those you have listed is wrong:

.docx

application/vnd.openxmlformats-officedocument.wordprocessingml.document

See http://www.w3schools.com/media/media_mimeref.asp .

xls is application/vnd.ms-excel , ppt is application/vnd.ms-powerpoint .

由于大多数请求的类型都是与Microsoft Office相关的，所以这个链接具有所有的办公室MIME类型（目前我发现的最重要的源代码）：http://filext.com/faq/office_mime_types.php
