Ok, I did this, and it prints out the array of project stuff, however,
it doesn't seem to be saving the sub-project array in the array. The
two projects with sub projects have the same structure as those with no
sub projects. Here is an example of two projects, one with a sub
project, one without:

Array ( [1] =>

Array ( [0] => CATPA [1] => Curation Analysis Tool for Protein
Alignments [2] => [3] => As the genomes of more organisms become fully
sequenced, there will be a greater opportunity to understand the
function, structure, and evolution of genes. Typically, blah, blahblah.
[4] => 34 [5] => )

[14] => Array ( [0] => Regulatory Elements [1] => Regulatory Elements
[2] => [3] => Transcriptional factors regulate gene expressions by
binding to elements in DNA sequences. These regulatory elements are ofen
short (about 4-15 nucleotides long), hidden in the background of nearly
random DNA sequences, which make their identification difficult. blah,
blahblah. [4] => 0 [5] => )

)

Looks like the structure is:

[14] (project_id) => Array ( [0] => short_name [1] => title [2]
=>short_description [3] => description [4] => file_id [5] =>
parent_project_cd)

I'm sort of at a loss. I don't see any column names in the array, which
I thought would be there, and it looks like adding the subs to the array
did not work, either.
