While I get some warnings regarding undefined tags, I get
otherwise expected output from exit_read_data():
<https://gist.github.com/cmb69/83eddfa74f133cc6fd3848cba54e5772>

Are you sure that you are using PHP 7.4.13, and that the provided
image fails for you?

Description:
------------
I upload image to process with

exif_read_data

with some photos result is:

""" exif_read_data(php80D2.tmp): Process tag(xE6FA=UndefinedTag): Illegal format code
0x2035, suppose BYTE in ... [FILE] + [LINE] """

I see:
https://bugs.php.net/bug.php?id=40073
and others.

Test script:
---------------
	$finfo = finfo_open(FILEINFO_MIME);
	$FT = finfo_file($finfo, $_FILES['img']['tmp_name']);
	finfo_close($finfo);
	if(preg_match('/image/i', $FT)){
		if(preg_match('/jpeg|jpg/i', $FT)){
			$FT = exif_read_data($_FILES['img']['tmp_name']);


just LAST LINE = error


Expected result:
----------------
ARRAY with DATE of creation, width, size, name, etc...

Actual result:
--------------
exif_read_data(php80D2.tmp): Process tag(xE6FA=UndefinedTag): Illegal format code 0x2035, suppose
BYTE in ... [FILE] + [LINE]
