ID: 55182 Comment by: narf at bofh dot bg Reported by: dominique at ramaekers-stassart dot be Summary: finfo_file() doesn't detect right mime-type Status: Open Type: Bug Package: Unknown/Other Function Operating System: Ubuntu 10.04 PHP Version: 5.3SVN-2011-07-11 (SVN) Block user comment: N Private report: N New Comment: AFAIK, this is depends on the OS and external packages. MIME type detection isn't a problem just for PHP and I doubt there's much that can be done about it. Previous Comments: ------------------------------------------------------------------------ [2012-08-14 19:58:38] tom at tombartling dot com This also fails to detect the correct mime-type for PHP files. If the file starts with <?php, it returns text/x-php as the mime-type. If the file starts with <!DOCTYPE html><html>... and the PHP code is anywhere else in the file, it returns text/html as the mime-type. It fails to detect a CSV file correctly. This is a problem for the CodeIgniter framework, since it's file upload class uses this function. I'm on Red Hat Enterprise Linux Server release 5.8 (Tikanga). ------------------------------------------------------------------------ [2011-07-11 16:33:30] dominique at ramaekers-stassart dot be Description: ------------ The finfo_file command detects openxml documents (xlsb, xlsx,...) as application/zip files. Can this be fixed? There are a lot of people who have to hack the mediawiki code to allow these files for upload. With these hacks they lose a part of there security: the checking of the finfo_file-mime-type against the file extension itself... Test script: --------------- php > $finfo = finfo_open(FILEINFO_MIME_TYPE); php > echo finfo_file($finfo, '/mnt/Transfert/test.xlsb'); application/zip ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55182&edit=1
