From: http://www.php.net/manual/en/language.constants.php
Only scalar data (boolean, integer, float and string) can be contained
in constants.
----------
somewhere in the manual it is said that while a resource or link or
some such identifier might look like an integer, it actually isn't.
So by extension it is not a scalar value and thus cannot be stored via
the means of a define().
Use a 'normal' variable instead.
