what i completly don't understand is why PHP obviously brings it's on mime-magic and
static implementation instead just use the operating systems file-libs

Description:
------------
i have at least one GIF image with 2.3 MB which is detected as application/octet-stream while
'/usr/bin/file -b --mime-type' on the same machine correctly results in image/gif

sadly i don't see here any option to attach the image :-(
that makes it hard to implement relieable checks if the
extension of uploads matchs the expected mime-type

[harry@srv-rhsoft:~/Desktop]$ php mime.php 
/usr/bin/file -b --mime-type
image/gif

finfo_file(filename, FILEINFO_MIME_TYPE)
application/octet-stream


Test script:
---------------
#!/usr/bin/php
<?php
 echo '/usr/bin/file -b --mime-type' . "\n";
 passthru('/usr/bin/file -b --mime-type ' . escapeshellarg(__DIR__ . '/1.gif'));
 echo "\n";
 echo 'finfo_file(filename, FILEINFO_MIME_TYPE)' . "\n";
 $finfo_handle = finfo_open();
 echo finfo_file($finfo_handle, __DIR__ . '/1.gif', FILEINFO_MIME_TYPE) . "\n";
 finfo_close($finfo_handle);
?>

Expected result:
----------------
image/gif as result

Actual result:
--------------
application/octet-stream as result
