Please don't send to my direct email. I read the forums regularly enough.

Hi Everyone,
I am at loss so I am hoping your wisdom can help me.
I originally had a script that first got a list of terms to be searched
from the file uploaded in the first part. This list is stored in the array
$snp. Every item in $snp occurs once for every entry i have in the table.
The goal is to allow the user to select a set in the file uploaded and get
every entry for a given project, which is entered via POST.
I had originally wrote this in way that it made 3 or 4 calls to the
database and it was way to slow, so I tried to make one call to the
database and put everything in a multidimensional array.
Now, what I have below seems to work, but I get 3notices for every
iteration of the foreach($rows as $ids) and I can't figure out for the life
of me why.

I guess I would like to know what it is going on out of curiosity and if it
can cause a problem down the road. Also, any suggestions on improvement are
always welcome.

move_uploaded_file($_FILES['snps']['tmp_name'], "$dir/$filename");
echo "Uploaded file '$filename' <br />";

}
