php解析JSON与XML数据的实现代码

$json_string='{"id":1,"name":"foo","email":"foo@jb200.com","interest":["wordpress","php"]} ';
$obj=json_decode($json_string);
echo $obj->name; //prints foo
echo $obj->interest[1]; //prints php

$xml_string="<?xml version='1.0'?>
<users>
<user id='123'>
<name>Test</name>
<email>test@jb200.com</name>
</user>
<user id='345'>
<name>News</name>
<email>fnews@jbxue.net</name>
</user>
</users>";

//load the xml string using simplexml
$xml = simplexml_load_string($xml_string);

//loop through the each node of user
foreach ($xml->user as $user)
{
//access attribute
echo $user['id'], ' ';
//subnodes are accessed by -> operator
echo $user->name, ' ';
echo $user->email, '<br />';
}
