A small example of php parsing JSON and XML

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

2、解析XML 数据

I)、xml文件

$xml_string="


Foo
foo@bar.com


Foobar
foobar@foo.com

";

II)、解析xml的代码

//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, '';
}
?>
