Is it possible to call a function from inside a heredoc?

For example, if I wanted to call date('Y-m-d', $rwTrans['dateTime']) inside the heredoc:-
    echo <<<EOD
      <tr data-transID="{$rwTrans['transID']}">
        <td>{date('Y-m-d', $rwTrans['dateTime'])}</td>
        <td>$transNote</td>
        <td>{$rwTrans['amount']}</td>
        <td>{$rwTrans['status']}</td>
      </tr>
EOD;

Any ideas?

It doesn't work that way.  You get variable substitution in HEREDOC, but not function calls.  So call the function outside of the HEREDOC, set a variable, and use the variable in the HEREDOC block.  Something like this...
    // THIS ASSUMES THAT $rwTrans['dateTime'] CONTAINS A UNIX TIMESTAMP
    $datexxx = date('Y-m-d', $rwTrans['dateTime']);
    
    echo <<<EOD
      <tr data-transID="{$rwTrans['transID']}">
        <td>$datexxx</td>
        <td>$transNote</td>
        <td>{$rwTrans['amount']}</td>
        <td>{$rwTrans['status']}</td>
      </tr>
EOD;
