I cannot reproduce this error, in addition, our use of the underlying API (magic_stream)
doesn't seem to allow us to cause this, the only thing I can think of is that maybe the magic
database is somehow corrupted, but this seems highly unlikely.
Running the script as it was is not possible from my location, and so probably the same is true for
others.
I suggest you upload the image to a globally accessible location, and suggest you expand the test
script to include buffer (string) and stream (resource) usages.

I created a repository on github which tests this bug against PHP 7.2, 7.3 and 7.3RC1 inside docker
containers: https://github.com/jdoubleu/php-bug-78183
The issue only affects PHP 7.2

Description:
------------
The finfo_file() method does not return the correct mime-type for .tga files.
Test script:
---------------
ini_set('user_agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36
(KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36');
$src = fopen('http://people.math.sc.edu/Burkardt/data/tga/earth.tga',
'r');
$dest = fopen('image.tga', 'w');
stream_copy_to_stream($src, $dest);
print(finfo_file(finfo_open(FILEINFO_MIME_TYPE), 'image.tga'));
// => image/x-tgaimage/x-tga
Expected result:
----------------
"image/x-tga"
Actual result:
--------------
"image/x-tgaimage/x-tga"
