How is this a dupe?
I am getting unexpected output (even when using the STFU operator).
The dupe is about getting an unexpected fatal error.
Am I missing something here?

Description:
------------
The imagecreatefromjpeg function improperly handles errors when passing a corrupt jpeg image.
Not only does it still output an error (coming from gd directly I guess), but it also spits out 3
PHP errors (1 notice and 2 warnings).
Test script:
---------------
Test image can be found at https://pieterhordijk.com/broken-mspaint.jpeg
@imagecreatefromjpeg('/path/to/broken-mspaint.jpeg');
imagecreatefromjpeg('/path/to/broken-mspaint.jpeg');
Expected result:
----------------
First call with the STFU operator should output nothing.
Second call without the STFU operators should probably just give one single php error instead of 3
Actual result:
--------------
First call with the STFU operator:
JPEG datastream contains no image
Second call without the STFU operator:
PHP Notice: imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Corrupt JPEG data: 947
extraneous bytes before marker 0xd9
in /path/to/test.php on line 5
PHP Warning: imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error: in
/path/to/test.php on line 5
JPEG datastream contains no image
PHP Warning: imagecreatefromjpeg(): '/path/to/image/broken-mspaint.jpeg' is not a valid
JPEG file in /path/to/test.php on line 5
