PHP把相对复杂结构的XML转换成数组。

inushome

这个问题纠结了半上午，看网上也没有什么特别有帮助的文章，我就发出来和大家共享一下吧。

<?php
$xml = simplexml_load_file ( "data.xml" );
$result = $xml->xpath ( "Control" );
foreach($result as $key=>$r)
{
unset($a);
unset($pro_attr);
unset($pro_a);
$a[ID]=(int)$r[ID];
$a[Type]=(string)$r[Type];
foreach($r->Property as $k=>$p)
{
$pro_a[Name]=(string)$p[Name];
$pro_a[Type]=(string)$p[Type];
$pro_a[Value]=(string)$p[Value];
$pro_attr[(string)$p[Name]]=$pro_a;
}
$a[property]=$pro_attr;
$attr[]=$a;
}
print_r($attr);
?>

本来呢，用ECHO输出那个$return的项结果得出来 的值 是正确的，以为取出来本来就是数组，但用print_r打印输出发现都是simplexmlelement object对象，这不是我想要的，我想要的是这样的

终于想到了转型，即然输出的是正确的那么我们利用PHP的弱数据类型 的特点把它转型行不行呢？试了一下，果不其然。然后用循环把它输入到数组中保存，结果就是这样的，这种XML中有属性，有子节点，当也可以是更复杂的结构，可以以些类推。
