PHP Version 5.2.6
The bug is found everytime.
My workaround is to put the condition between ().

Here is the phpinfo page:

Test script:

//Exemple:

//1)
echo "Step 1)\n<br/>";
unset($foe);
echo $foe ? "bar" : "foe" . " days";
//This will echo "foe"

//2)
echo "Step 2)\n<br/>";
unset($foe);
echo ($foe ? "bar" : "foe") . " days";
//This will echo "foe days"

//Please check if it would be possible that step 1) will ever work somedays?

Expected result:
----------------
Step 1) should echo "foe days".
Step 2) echo "foe days".

Actual result:
--------------
Step 1) echo "foe".
Step 2) echo "foe days".

Are you sure? I downloaded the same old version of PHP and the step 1 code always echos "foe days", correctly, NEVER "foe".

In case you mixed up your strings, it will produce just "bar" rather than "bar days" if $foe is set, yes, but that is not a bug. See the operator precedence table:
http://www.php.net/manual/en/language.operators.precedence.php

'?:' occurs lower down the table than '.', which means concatenation is considered first. So this expression:

$foe ? "bar" : "foe" . " days"

is considered as if it were this:

$foe ? "bar" : ("foe" . " days")

So it will evaluate to either "bar" or "foe days".

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.
