php数组转xml

Posted 2020-11-10

1. 代码：

   <?php
   function arraytoxml($arr = array(),$charset=‘utf8‘) {  
   $xml  =‘<!--xml version="1.0" encoding="‘.$charset.‘" -->‘;
   $xml .= change($arr);
   return $xml;
   }
   function change($source) {
   $string="";
   foreach($source as $k=>$v){
       $string .="<".$k.">"; 
       if(is_array($v) || is_object($v)){
           $string .= change($v);
       }else{ 
           $string .=$v;
       } 
       $string .="</".$k.">";
   }
   return $string;
   }

2. 测试：

   $arr = array(
   ‘name‘ => array(
       ‘a‘ => ‘aa‘,
       ‘b‘ => ‘bb‘
   )
   );
   $xml = arraytoxml($arr);
   echo $xml;

3. 输出：

   <!--xml version="1.0" encoding="utf8" --><name><a>aa</a><b>bb</b></name>
