Here it is, with '...' added in for brevity
:)
Yes, both of those were added deliberately. There aren't any ellipses in the actual scripts.
Here is session.php in its entirety, save for some variables that I'd like to keep secret and some lengthy block comments. In this file (though it cannot be run), the error would occur at line 262, so I believe the problem is somewhere in 178-261.
