    __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.

    [Someone remove that other Patanjali's note, because it has errors! :-(]

    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.
