本文章给来大家讲一下关于PHP下simplexml使用方法,希望通过此文章能提升大家对simplexml操作xml文档的理解,有需要了解的朋友可参考.

PHP XML处理XML代码如下:

php解决xml代码,代码如下:

 
 
使用simpleXML处理XML
getName(); //var_dump($xml->children()); $record = ''; foreach ($xml->children() as $child) { $record.= ''; foreach ($child->children() as $item) { //var_dump($child); $record.= ''; } $record.= ''; } echo $record; ?>
name price description calories
' . $child->attributes() . '' . $item . '

将XML转换为数组结构,代码如下:

private function change_simple_xml_to_array($obj){ 
  $i = 0; 
  //从根节点下的二层子节点开始遍历 
  foreach($obj->children() as $value){ 
    //如果发生同级、同标签名的情况,则加一维数组; 
    if(isset($last_name) && $value->getName()==$last_name){ 
      //出现同名发现第二个,则推入第二维数组; 
      if($i==1) $arr[$last_name]=array($arr[$last_name]); 
      //遍历子节点; 
      array_push($arr[$last_name],$this->change_simple_xml_to_array($value)); 
    }else{ 
      $last_name = $value->getName(); 
      if(count($value->children())==0) $arr[$last_name] = $value.""; 
      else $arr[$last_name] = $this->change_simple_xml_to_array($value); 
    } 
    $i++; 
  } 
  return $arr; 
}

        ) 
 
      [1] => Array 
        ( 
          [user] => baidongdaogu 
          [pas] => aaa 
          [permission] => 1 
          [online_time] => 2 
        )

          [online_time] => 2
