Define new variable created by FOREACH

Hello all,

I have a multi record table, which includes the field 'email_address', and have a display page showing this:

<?php foreach ($contactsRecords as $record): ?>
<?php echo $record['email_address'] ?>
<?php endforeach; ?>


I need to be able to assign the output to a new variable, such as:
$allemails = email@email.com, email2@email.com, email3@email.com

So I can then on a subsequent page display:
"email@email.com, email2@email.com, email3@email.com".

I need to assign it to the new varaible ($allemails) so it can indeed be displayed/posted into a subsequent page.



The code
<?php $recipients = '<?php foreach ($contactsRecords as $record): ?><?php echo $record['email_address'] ?><?php endforeach; ?>' ?>

Is the principle, but obviously doesn't work as I'm trying to put <?php> tags within already open <?php> tags.

I've tried it cutting out the second set of tags, but still doesn't work.

So i'm not sure if it's just a slight error with my line, or i'm barking up the wrong tree...

I touched in the Concatenation idea, but not sure how to make it concatenate FOREACH.

Any ideas/thoughts would be most appreciated.

Many thanks
Rob
