New Comment:
Once again your script doesn't run. There is a syntax error.
Plus, of course you get a warning with:
if (!isset($var)) echo $var;
The warning is on the echo of a variable that hasn't been set, not on
the check itself. Until you provide an actual sensible script that you
have run before submitting it, please don't waste any more of our time.

You're right, my mistake - my original script had it more like the
following:
<?php
function doX(){ return 'ok' };
if (!isset($var)) echo $var;
if (empty($var)) echo $var;
echo (!isset($var)) ? doX() : $var;
echo (empty($var)) ? doX() : $var;
?>
Both generated the Notice)

That is a completely bogus test script. Did you even bother to try
running it? You can't have an echo there and you are claiming an
undefined index warning in a script that doesn't even have an index.

Already included it... but I'll expand on it...
<?php
function doX(){};
(!isset($var)) ? doX() : echo $var;
(empty($var)) ? doX() : echo $var;
?>
Above code with E_NOTICE enabled.)

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
A version of this bug was reported last year that was marked bogus (Bug
#45760: Notice: Undefined index "?:" operator), however, there is an
error in this that is not bogus:
(isset($var)) ? doX() : echo $var;
(empty($var)) ? doX() : echo $var;
These return an undefined index even though it's being checked for.
(CentOS)
Also note that the notice in legitimate cases is still undocumented on
the alternate control structures page.
Reproduce code:
---------------
(!isset($var)) ? doX() : echo $var;
(empty($var)) ? doX() : echo $var;
Expected result:
----------------
No "Notice: Undefined index"
Actual result:
--------------
"Notice: Undefined index"
------------------------------------------------------------------------
