Problem using foreach to loop pdo results

Here is the scenario. On my local vm this works great. but on the production server does not work.

My VM where the code works:
uname -a
Linux dev 3.13.0-65-generic #106-Ubuntu SMP Fri Oct 2 22:08:27 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
root@dev:/var/www# php -v

Open in new window

The Production server:
uname -a
Linux  2.6.32-573.8.1.el6.x86_64 #1 SMP Tue Nov 10 18:01:38 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

At first glance, your code looks correct to me, but it's a data-dependent problem, so we would need to see the data.

When you try to print a PHP array (or otherwise convert it to a string) PHP returns "array."  Not very helpful!

Here is the man page for fetchAll():

Try looking directly at the raw data.  You can use var_dump($results) to see what the data structure looks like.
