no you can't, store the results of calculation and function calls in
variables and use them in the HEREDOC statement.

a HEREDOC declaration is just a string declaration like these:

$s = 'foo';
$t = "bar";

they can't contain expressions, function calls or anything like that.

Same way as you do with "" strings. e.g.

<?php
class foo {
  function bar() {
    return 'world!';
  }

  function hello() {
    echo <<<ENDHELLO
Hello, {$this->bar()}
ENDHELLO;
  }
}

$foo = new foo();
$foo->hello();
?>

Like I tell my dogs "Don't do it inside".

Place your decision making outside of the herdoc and then branch to
whatever heredoc you want.

My advice,
