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).
