mail function

I need to make an email link in a table. The username is displayed as text; I need it to be a link through which I can send email. Is this possible in php? The following is the code for that I'm using: function show_logged_users($user) { $query = "select distinct uid, cn from log left join ldap.ldap on log.user like ldap.ldap.uid order by ldap.ldap.sn"; connect(); $result = mysql_query($query); if (($result) && (mysql_num_rows($result) > 0)) {

    while ($line = mysql_fetch_row($result)) {
      $opts[$line[0]] = $line[1];
    }

} else {

    $opts[0] = "Error in show_logged_users()";

} show_select($opts, $user); } <td>

    <font face="Arial, Helvetica, sans-serif" size="-1" color="#FFFFFF"><b>User</b></font>

</td> <td>

    <select name="user">
    <? show_logged_users($user) ?>
    </select>

</td> What I need is the <? show_logged_users($user) ?> statement to turn itself into a mailto: statement to that clicking on the user name will bring up an email addressed to username @domain.com Is this possible? Is there any code out there that I can get a look at? Thanks, Liz
