Right. exif_read_data() is normally used together with error suppression (@), unless you
specifically want to debug why some EXIF results are missing or similar. Warnings from this
functions are generally harmless, as long as you still get back a result.

Maybe this should be documented though?

>>> disable your error handler

The police in company is
"NO HIDDEN ERRORS / PREVENT ERRORS"

>>> Silence the exif_read_data() call using the @ operator
ah!,
then becouse exist this option, my report:
[NO'T is a BUG]

true?

Silence the exif_read_data() call using the @ operator, or disable
your error handler.

@requinix@php.net I was download PHP 7.4.13 and the error is IDENTIC:

<b>Notice</b>:  exif_read_data(phpD7AA.tmp): Potentially invalid endianess, trying again
with different endianness before imminent failure. in FILE, LINE

Then my script return EMPTY data.

Identic situation running php-7.4.5
Identic situation running php-8.0.0
