#42355 [Bgs]: can't concatenate when defining class constant
ID: 42355
User updated by: adam dot huttler at fracturedatlas dot org
Reported By: adam dot huttler at fracturedatlas dot org
Status: Bogus
Bug Type: Class/Object related
Operating System: Linux
PHP Version: 5.2.3
New Comment:
Thanks for the reply. I suspected this would be marked bogus, since the
behavior is consistent with how object properties need to be
initialized, etc.
Can this be considered a feature request? I do understand the
runtime/compile time challenge. But it seems like there may be ways
around it (e.g. late static binding is getting addressed).

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
You can only initialize class constants with constant values. You pass
a statement which has to be evaluated at runtime, while the class
constants are defined at compile time which comes earlier.

Description:
------------
When defining a global constant, you can concatenate a string to
another constant. Doing this with class constants causes a parse error.
If this isn't considered a bug, please consider it a feature request,
as it would be very useful for configuration (especially file paths).
Thanks.
Reproduce code:
---------------
define('FOO', 'foo');
class Foobar
{
const MESSAGE = FOO . 'bar';
}
echo Foobar::MESSAGE;
Expected result:
----------------
foobar
Actual result:
--------------
Parse error: syntax error, unexpected '.', expecting ',' or ';'
------------------------------------------------------------------------
