File excel not recognized

[Defacta]

Hi,

When I upload an excel file, PHP does not recognize the type of this
file:

echo $HTTP_POST_FILES['file']['type'] ;

returns: application/octet-stream
Whereas a word file returns: application/msword

Do you know if there is anyway to get the type of a excel file ?

Thanks,
Vincent.

Hi Vincent,

From http://nl3.php.net/manual/en/features.file-upload.php

------------------------------------------------------------------------
$_FILES['userfile']['type']

The mime type of the file, if the browser provided this
information. An example would be "image/gif". This mime type is however
not checked on the PHP side and therefore don't take its value for granted.
------------------------------------------------------------------------

Bottomline: don't rely on this.
And the value application/octet-stream just means it is a binary file,
which is correct in this case, but little informative.
