PHP数组与XML之间的转换

Jun 23, 2016 pm 01:03 PM

在开发中,我们经常会遇到数组与XML之间的互相转换,尤其在处理接口开发的时候经常用到,比如对方客户端POST一个XML格式的数据到服务器上,服务器上的程序要负责接收解析,还有需要将数据表数据以XML格式提供给第三方等等应用。

下载源码

本文我们将简单介绍如何使用PHP处理数组和XML之间的互相转换。

PHP将数组转换成XML

PHP可以将数组转换成xml格式,简单的办法是遍历数组,然后将数组的key/value转换成xml节点,再直接echo输出了,如:

function arrayToXml($arr){    $xml = "<root>";    foreach ($arr as $key=>$val){    	if(is_array($val)){        	$xml.="<".$key.">".arrayToXml($val)."</".$key.">";        }else{        	$xml.="<".$key.">".$val."</".$key.">";        }    }    $xml.="</root>";    return $xml;}
Copy after login

我测试了下,这个最简单,速度又快,支持多为数组,中文也不会乱码。

另一种方法是利用DOMDocument来生成xml结构:

function arrayToXml($arr,$dom=0,$item=0){    if (!$dom){        $dom = new DOMDocument("1.0");    }    if(!$item){        $item = $dom->createElement("root");         $dom->appendChild($item);    }    foreach ($arr as $key=>$val){        $itemx = $dom->createElement(is_string($key)?$key:"item");        $item->appendChild($itemx);        if (!is_array($val)){            $text = $dom->createTextNode($val);            $itemx->appendChild($text);                    }else {            arrayToXml($val,$dom,$itemx);        }    }    return $dom->saveXML();}
Copy after login

它同样可以将数组转换成xml,而且支持多维数组,生成的xml中文也不会乱码。

PHP将XML转换成数组

做接口开发的时候经常会碰到别人提交给你的是xml格式的数据,常见的微信接口、支付宝接口等,他们的接口如发送消息通信都是xml格式的,那么我们先想办法拿到这个xml数据,然后再将其转化成数组。

假设我们获取到一个这样的XML:

<root><user>月光光abcd</user><pvs>13002</pvs><ips><baidu_ip>1200</baidu_ip><google_ip>1829</google_ip></ips><date>2016-06-01</date></root>
Copy after login

通过simplexml_load_string()解析读取xml数据,然后先转成json格式,再转换成数组。

function xmlToArray($xml){        //禁止引用外部xml实体    libxml_disable_entity_loader(true);    $xmlstring = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA);    $val = json_decode(json_encode($xmlstring),true);      return $val;}
Copy after login

调用xmlToArray()可得到以下结果:

得到数组后,我们就可以对数据进行各种处理了。
