Conditional statements in php heredocs syntax?

I was wondering if you can have conditional statuses inside heredocs, this is my script, but it deosnt correctly parsed $ username?

php code:

function doSomething($username) {

if (isset($_SESSION['u_name'])){
$reply ='<a class ="reply" href="viewtopic.php?replyto=@$username.&status_id=$id&reply_name=$username"> reply </a>';

return <<<ENDOFRETURN

$reply

ENDOFRETURN;

the problem with this is the $ username variable that deosnt gets in html. it remains $ username :)) thanks

Do you want to have conditional statements in heredoc or are you wondering why your code is not working? Since you currently do not have a conditional statement inside the heredoc, but this is still not possible.

, :
heredoc, $reply , . :

$reply ='<a class ="reply" href="viewtopic.php?replyto=@' . $username . '.&status_id=$id&reply_name=' . $username . '"> reply </a>'

, heredoc , return $reply ;) ( ).
