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
