一個簡短的：

<?php

$test_array = array (
  'bla' => 'blub',
  'foo' => 'bar',
  'another_array' => array (
    'stack' => 'overflow',
  ),);$xml = new SimpleXMLElement('<root/>');array_walk_recursive($test_array, array ($xml, 'addChild'));print $xml->asXML();

結(jié)果

<?xml version="1.0"?><root>
  <blub>bla</blub>
  <bar>foo</bar>
  <overflow>stack</overflow></root>

鍵和值是交換的-您可以用array_flip()在數(shù)組行走之前。array_walk_recursive需要PHP 5。你可以用array_walk相反，但你不會'stack' => 'overflow'在XML中。

下面是php5.2代碼，它將任意深度的數(shù)組轉(zhuǎn)換為XML文檔：

Array(
    ['total_stud']=> 500
    [0] => Array
        (
            [student] => Array
                (
                    [id] => 1
                    [name] => abc                    [address] => Array
                        (
                            [city]=>Pune
                            [zip]=>411006
                        )                       
                )
        )
    [1] => Array
        (
            [student] => Array
                (
                    [id] => 2
                    [name] => xyz                    [address] => Array
                        (
                            [city]=>Mumbai
                            [zip]=>400906
                        )   
                )

        ))

生成的XML如下：

<?xml version="1.0"?><student_info>
    <total_stud>500</total_stud>
    <student>
        <id>1</id>
        <name>abc</name>
        <address>
            <city>Pune</city>
            <zip>411006</zip>
        </address>
    </student>
    <student>
        <id>1</id>
        <name>abc</name>
        <address>
            <city>Mumbai</city>
            <zip>400906</zip>
        </address>
    </student></student_info>
