Edit report at https://bugs.php.net/bug.php?id=79681&edit=1 ID: 79681 Updated by: cmb@php.net Reported by: xandros92 at gmail dot com Summary: mime_content_type/finfo returning incorrect mimetype -Status: Feedback +Status: Analyzed Type: Bug Package: *Directory/Filesystem functions Operating System: Windows 10 1909 PHP Version: 7.4.6 Assigned To: cmb Block user comment: N Private report: N New Comment: Thanks for the samples! I can confirm the behavior. Reporting the .xml.gz as application/gzip is actually an improvement, since this mime type is registered[1]. Reporting the .mp3 as application/x-font-gdos is obviously wrong, and has been fixed[2] for file 5.38.
