The third one is not equivalent to the former two; the outer single quotes 
prevent variable expansion.  It would have to be

  echo '<option value="' . $some_var_name . '">some text</value>';

Another possibility are HereDoc strings:

  echo <<<HTML
<option value="{$some_var_name}">some text</value>
HTML;

Do not forget htmlspecialchars($some_var_name) in any case!

Mark the last sentence which is essentially what Denis said, and consider 
that XML-based document types *require* the quotes (for well-formedness).
