PHP 的xml 操作类有多种,xml to array 的方法当然也是有多种的,一般常见的就是递归遍历。今天看了一下php 的手册,然后发现评论中有很多新颖的用法,尽管有些不是很完善。这里列举几个。

//2 line XML2Array
$xml?=?simplexml_load_string($xmlstring);
$array?=?json_decode(json_encode($xml),TRUE);
//完善过的
function?toArray($xml) {
? ? ? ??$array?=?json_decode(json_encode($xml),?TRUE);
? ? ? ??
? ? ? ? foreach (?array_slice($array,?0) as?$key?=>?$value?) {
? ? ? ? ? ? if ( empty($value) )?$array[$key] =?NULL;
? ? ? ? ? ? elseif (?is_array($value) )?$array[$key] =?toArray($value);
? ? ? ? }
? ? ? ? return?$array;
? ? }
//2 line XML2Array 利用强制类型转换
$xml = simplexml_load_string($file);
$array = (array)$xml;
