Description:
------------
Documentation at http://www.php.net/manual/en/function.parse-ini-file.php says "Constants may also be parsed in the ini file so if you define a constant as an ini value before running parse_ini_file(), it will be integrated into the results. Only ini values are evaluated.". 

I found this to be incomplete. Not only ini values are evaluated, but also section names.

Test script:
---------------
define( 'MYCONST', 1 );
/*
test.ini file looks like this

[MYCONST]
MYCONST = MYCONST

*/
$ret = parse_ini_file( 'test.ini', true );
var_dump( $ret );

Expected result:
----------------
array(1) {
  ["MYCONST"]=>
  array(1) {
    ["MYCONST"]=>
    string(1) "1"
  }
}

Actual result:
--------------
array(1) {
  [1]=>
  array(1) {
    ["MYCONST"]=>
    string(1) "1"
  }
}
