well, in a perfect world on would be able to update 'data_file.c' with the script in the
source tree before compile PHP, in the real world the file is updates, php builds but it don't
work
what about someone takes afte rmore than a year a look why https://access.thelounge.net/harry/php-mimetype-bug.gif
is recognized as application/octet-stream instead image/gif and considers to update the mime
database?
i don't get all the excuses for not use the system libmagic - for open_basedir and
streams-support one would need nothing else than a tiny wrapper doing that all with a tempfile which
ins finally feeded to the system libmagic instead fork it completly

me) PHP never has seen

@rhsoft PHP uses a patched libmagic primarily to a) integrate with PHP filesystem APIs, including
things like stream wrappers, but more importantly also open_basedir restrictions etc and b) to use
our per-request allocator. If you're interested in what the differences are, have a look at https://github.com/php/php-src/blob/master/ext/fileinfo/libmagic.patch.

as said i build PHP from the unpatched upstream sources, so the libmagic is bundeled and that exists
from 5.5.13 until 5.6.11 while the file-package from Fedora (cli command file) recognizes it
correctly, hence i even wrote admin scripts calling the file-cli from PHP
the problem is that at least for Fedora the distributions file-package becomes often updates in case
of bugs and wrong recognized samples and PHP is always behind :-(

Thanks for making the file available, and sorry for the bad
pointer to picpaste.com.
Anyhow, a quick check:
cmb@debian64:~$ file -b --mime-type 67516.gif
application/octet-stream
cmb@debian64:~$ dpkg -s file
Package: file
Status: install ok installed
Priority: standard
Section: utils
Installed-Size: 119
Maintainer: Christoph Biedl <debian.axhn@manchmal.in-ulm.de>
Architecture: amd64
Multi-Arch: foreign
Version: 1:5.22+15-2
Depends: libc6 (>= 2.4), libmagic1 (= 1:5.22+15-2), zlib1g (>= 1:1.1.4)
Description: Determines file type using "magic" numbers
File tests each argument in an attempt to classify it. There are
three sets of tests, performed in this order: filesystem tests,
magic number tests, and language tests. The first test that
succeeds causes the file type to be printed.

Which version of file/libmagic do you use?
