using array's with form?

Anon

I would really appreciate any help with this one...

I have a multi-answer checkbox in a form;
I would like to empty the contents of the array into a database table (perhaps as a string) so that I can retrieve them later.
At the moment the code returns Array.

Ive used this code to list the selected elements however, I do not wish to print them rather create a string and insert this info into Mysql.

// use a "for" loop to read and display array elements

for($count = 0; $count < sizeof($you); $count++)
{
echo "<i>$you[$count]</i><br>";
}

Where do I go from here? Much Thanks;
Chris

$temp = "";
for($count = 0; $count < sizeof($you); $count++)
{
$temp .= "$you[$count],";
}
$temp = substr($temp, 0, (strlen($temp)-1));

That will give you a comma separated list of all of the element inside the array $you.

I need to determine on my PHP4 code a way to determine if a user has checked a specific number of items in a form. My HTML has 3 checkboxes and I want the user to select only 2 choices. If they check more than 2 then I want to echo a message telling them they can only check 2.

I was thinking of using an array along with a for loop to determine this validation.

Can you please help?
