Question : PHP for loop - help with POST data

Hi Experts,

This is my problem:

I'm posting a set of variables from one page (index.php) to a second page (confirm.php).

On the first page, I have a dynamically created set of checkboxes, the number of vars posted to the second page is not known.

When index.php is submitted, I need to capture the values from the checkboxes. I have named them "option1" through to however many, i.e. "option8".

I have ascertained that I need a for loop but how do I capture the post values from these variable checkboxes?

Thanks

Here's a complete demo page that posts to itself and uses 'foreach' for the loop.
