PHP实现数组array转换成xml的方法

<?php$elementLevel = 0 ;function array_Xml($array, $keys = ''){global $elementLevel;if(!is_array($array)){  if($keys == ''){  return $array;  }else{  return "/n<$keys>" . $array . "</$keys>/n";  }}else{  foreach ($array as $key => $value)  {  $haveTag = true;  if (is_numeric($key))  {   $key = $keys;   $haveTag = false;  }  if($elementLevel == 0 )  {   $startElement = "<$key>";   $endElement = "</$key>";  }  $text .= $startElement;  if(!$haveTag)  {   $elementLevel++;   $text .= "<$key>" . array_Xml($value, $key). "</$key>/n";  }else{   $elementLevel++;   $text .= array_Xml($value, $key);  }  $text .= $endElement;  }}return $text;}$array = array("employees" => array("employee" => array(array("name" => "name one","position" => "position one"),array("name" => "name two","position" => "position two"),array("name" => "name three","position" => "position three"))));echo array_Xml($array);?>
