__toString() is not intended to be called directly.

Instead, it defines what is returned when the object is cast to string, either explicitly with:

(string)$element

Or implicitly, when used in certain contexts which would cause a conversion to string.

For those for whom it may not be immediately obvious from the example, the echo is what is forcing __toString() to be used.

However, to assign the text of a node (but not its children) to a variable:

$XML = new SimpleXMLElement('<p>Hello<span> world</span>.<span> Good day!</span></p>');

$Text = $XML->__toString();

is effectively:
$Text = 'Hello.'; // The <span>s are ignored.

Either of:
$Text = $XML->span->__toString();
$Text = $XML->span[0]->__toString();

is effectively:
$Text = ' world'; // Only the first <span> is used.

$Text = $XML->span[1]->__toString();

is effectively:
$Text = ' Good day!'; // Only the second <span> is used.
