PHP XML和数组互相转换

 1  
　　//数组转XML
 2     function arrayToXml($arr)
 3     {
 4         $xml = "<xml>";
 5         foreach ($arr as $key=>$val)
 6         {
 7             if (is_numeric($val)){
 8                 $xml.="<".$key.">".$val."</".$key.">";
 9             }else{
10                  $xml.="<".$key."><![CDATA[".$val."]]></".$key.">";
11             }
12         }
13         $xml.="</xml>";
14         return $xml;
15     }
16 

17     //将XML转为array
18     function xmlToArray($xml)
19     {    
20         //禁止引用外部xml实体
21         libxml_disable_entity_loader(true);
22         $values = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);        
23         return $values;
24     }
header("Content-type:text/html;charset=utf-8");
