2. Convert xml to json

Use simplexml

public function xml_to_json($source) {
if(is_file($source)){ //传的是文件，还是xml的string的判断
$xml_array=simplexml_load_file($source);
}else{
$xml_array=simplexml_load_string($source);
}
$json = json_encode($xml_array); //php5，以及以上，如果是更早版本，请查看JSON.php
return $json;
}

3. Convert json to xml

Use recursive function

public function json_to_xml($source,$charset='utf8') {
if(empty($source)){
return false;
}
//php5，以及以上，如果是更早版本，请查看JSON.php
$array = json_decode($source);
$xml ='';
$xml .= $this->change($array);
return $xml;
}
public function change($source) {
$string="";
foreach($source as $k=>$v){
$string .="<".$k.">";
//判断是否是数组，或者，对像
if(is_array($v) || is_object($v)){
//是数组或者对像就的递归调用
$string .= $this->change($v);
}else{
//取得标签数据
$string .=$v;
}
$string .="";
}
return $string;
}
