This sounds like exactly what I need. But, can you help me with the synatx?
I've read the entry in the PHP documentation and I don't completely
understand. Let's assume all of the code to define the HTML table
(including appropriate PHP) is stored in a database table called
FooterTable. The field containing the code is called FooterField.

Do I first need to assign the field to a variable via the eval()...

$vFooterText = eval(FooterTable['FooterField']);
echo $vFooterText;

or does the eval statement automatically include the ECHO...

eval(FooterTable['FooterField']);

or do I have to read the contents into a variable first, then eval(), then
echo...

$vFooterText = FooterTable['FooterField'];
eval($vFooterText);
echo $vFooterText;
