xml 怎样通过php解析到二维数组里面
$doc = new DOMDocument('1.0','utf-8');
$doc->load("config.xml");
$roots=$doc->documentElement;//获取根节点也就是config(仅有一个)
$childs=$roots->childNodes;//获取根节点下所有子节点也就是 db smarty
for($i=0;$ilength;$i++){ //按照根节点下的子节点数量进行循环存入数组
$config_item=$childs->item($i); //具体获得db smarty
$configs[$config_item->nodeName]=array();//将db smarty这两个子节点的名称作为数据存入数组中
$items=$config_item->childNodes; //获得db smarty下的所有子节点
for($j=0;$jlength;$j++){//按照db smarty下所有子节点数进行循环将db smarty下的子节点名与值以二维数组存入
$item=$items->item($j); //通过循环获取每个db smarty 下的子节点
$configs[$config_item->nodeName][$item->nodeName]=$item->nodeValue;
}//二维数组的书写
}
var_dump($configs);
