Hi Jason,
The code you pasted is littered with fatal errors and bugs (I
marked one example with ^^ above). Please paste a real
batch of code that you've tested and reproduces the error and
that will be much more helpful. The PHP version would be
helpful to know as well.

Production server will be PHP 5.1.2, developing on 5.0.5
I am also considering making my own 'project' object and having Folio have
an array of 'projects' rather than using the array of associative arrays.
Would this provide a solution?
Thanks,
Jason
If you're going to be using 5.1.2 in production, develop on 5.1.2. PHP
doesn't guarantee backwards compatibility, especially in such a big
change as 5.0.x - 5.1.x. Better to develop on 5.1.2 from the start than
to develop on 5.0.5, put the code on 5.1.2, get a bunch of errors, and
then have to develop again on 5.1.2 to fix the bugs. Not to mention that
any testing done with 5.0.5 is invalid since you can't be sure that
things will behave the same with the different production version. You
may even waste time working around bugs in 5.0.5 that don't exist in 5.1.2.
