I tried that, and then I realised that the userid for the user profile that is being viewed by the logged in user, is passed with a link using view_profile.php?id=userid, does this mean I can use something like the following?

echo 'a href="send_message.php?sendto=' . userid='$_GET[id] . '">' . userid='$_GET[id] . '';

Also, it's not using a mysql_fetch_array on this page, so not sure what the other ways to write this string. I looked at the link for PHP strings but there is nothing about a href and strings there.

You are missing some HTML

You are missing some HTML tag information, this should work:

<?php
echo '<a href="send_message.php?sendto=' . $row['userid'] . '">' . $row['name'] . '</a>';
?>

I am pretty sure you are fetching the rows as an array, so you access the user id with $row['userid'], not $row->userid.

You may want to look over the PHP manual page on Strings for more information on echoing strings as well as concatenation.
