Description:
------------
using the define() function I get a warning when I don't think I should.

Reproduce code:
---------------
define( "LOGIK_MYSQL_HOST", $config->getMySQLHost() );

where $config->getMySQLHost() returns a string.

The following code makes the warning go away:

define( "LOGIK_MYSQL_HOST", (string) $config->getMySQLHost() );

Expected result:
----------------
define( "LOGIK_MYSQL_HOST", $config->getMySQLHost() );

should not produce a warning

Actual result:
--------------
define( "LOGIK_MYSQL_HOST", $config->getMySQLHost() );

produces the following warning:

"Warning: Constants may only evaluate to scalar values"

even though $config->getMySQLHost() returns a scalar, have to cast to string in order to make the warning go away
