Bug description:Problem defining an array-type constant from a text file

Description:
------------
When defining a constant of type array from a text file, the (shorter
and case sensitive) const command doesn't work, it throws a "Fatal
error: Constant expression contains invalid operations in php shell code
on line XY" error.

The following test script is performed in the command line (php -a)

The first command throws:
Fatal error: Constant expression contains invalid operations in php
shell code on line 1

The second works fine and the third gives the following result:

Array
(
    [0] => Line 1
    [1] => Line 2
    [2] => Line 3
    [3] => ...
)


Test script:
---------------
const myArrayConst = file("mytextfile.txt", FILE_IGNORE_NEW_LINES);

define ("myArrayConst", file("mytextfile.txt", FILE_IGNORE_NEW_LINES));

print_r(myArrayConst);
