オブジェクト[オブジェクト]に要素を追加しますか？ 私は私が試してみましたAPPENDを使用して新しいオブジェクト[インデックス] => [$ i]の[$ jを][array]オブジェクトに要素を追加しますか？
SimpleXMLElement Object
(
[books] => Array
(
[0] => SimpleXMLElement Object
(
[book] => Array
(
[0] => SimpleXMLElement Object
(
[info] => SimpleXMLElement Object
(
[qty] => 12
[title] => C++
[index]=>[0][0]
)
)
[1] => SimpleXMLElement Object
(
[info] => SimpleXMLElement Object
(
[qty] => 21
[title] => PHP
[index]=>[0][1]
)
)
)
)
[1] => SimpleXMLElement Object
(
[book] => SimpleXMLElement Object
(
[info] => SimpleXMLElement Object
(
[qty] => 25
[title] => Java
[index]=>[1][0]
)
)
)
)
