php数组的问题

object(SimpleXMLElement)[1]
public 'book' =>
array (size=3)
0 =>
object(SimpleXMLElement)[2]
public '@attributes' =>
array (size=1)
...
public 'name' => string 'PHP' (length=3)
public 'price' => string '20.0' (length=4)
1 =>
object(SimpleXMLElement)[3]
public '@attributes' =>
array (size=1)
...
public 'name' => string 'XML' (length=3)
public 'price' => string '20.3' (length=4)
2 =>
object(SimpleXMLElement)[4]
public '@attributes' =>
array (size=1)
...
public 'name' => string 'C#' (length=2)
public 'price' => string '20.1' (length=4)



$xml = file_get_contents("book.xml");
$simple = new SimpleXMLElement($xml);

为什么不能使用$simple['book']['name'];这样取值，只能使用$simple->book->name这样呢。跪求大神解答下

回复讨论(解决方案)

因为是对象！
你不是也看到有 object(SimpleXMLElement) 吗？
object(SimpleXMLElement) 表示是一个 impleXMLElement 类型的对象

哦 明白了 谢谢大神

$simple = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);//这样就转成数组了
