php实现将数组转换为XML的方法

xml = new XmlWriter(); } function toXml($data,$eIsArray=FALSE) { if(!$eIsArray) { $this->xml->openMemory(); $this->xml->startDocument($this->version,$this->encoding); $this->xml->startElement($this->root); } foreach($data as $key => $value){

if(is_array($value)){
$this->xml->startElement($key);
$this->toXml($value,TRUE);
$this->xml->endElement();
continue;
}
$this->xml->writeElement($key,$value);
}
if(!$eIsArray) {
$this->xml->endElement();
return $this->xml->outputMemory(true);
}
}
}
$res = array(
'hello' => '11212','world' => '232323','array' => array(
'test' => 'test','b' => array('c'=>'c','d'=>'d')
),'a' => 'haha'
);
$xml = new A2Xml();
echo $xml->toXml($res);
