この関数は、兄弟を既存のノードに追加します。 The child can be created
with e.g.
DomDocument_create_element()
,
DomDocument_create_text()
etc. or simply by using any other node.
Before a new sibling is added it is first
duplicated. Therefore the new child is a completely new copy
which can be modified without changing the node which was
passed to this function. If the node passed has children
itself, they will be duplicated as well, which makes it quite
easy to duplicate large parts of a xml document. The return
value is the added sibling. If you plan to do further
modifications on the added sibling you must use the returned
node.
This function has been added to provide the
behaviour of
DomNode_append_child()
as it works till PHP 4.2.
