PHP使用stream_context_create（）返回XML

Question

I'm using stream_context_create() instead of cURL to make an HTTP post. It works, but file_get_contents() returns a single string of all the data instead of an XML object. How can I modify my code so it returns an XML object and I can access the values individually?

<?php
$url = 'http://www.domain.com';
$data = array( 'name1' => 'data1', 'name2' => 'data2', 'name3' => 'data3' );

$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query( $data )
    )
);

$context  = stream_context_create( $options );

$result = file_get_contents( $url, false, $context );

var_dump($result); // data1data2data3
?>

And the page that returns the XML:

<?php
header('Content-type: text/xml');

$xml = '<result><name1>' . $_POST['data1'] . '</name1><name2>' . $_POST['data2'] . '</data2><name3>' . $_POST['data3'] . '</name3></result>';

echo $xml;
?>

I think that you're looking at this var_dump in your browser, and browser tries to render tags <result> and <name..> as standard HTML.

Please try to run this code, and check the source of your webpage (in Chrome, you can do it by prepending page URL by view-source: )
