simplexml_import_dom - 不起作用

Question

if (file_exists('http://something_from_a_url.xml')) {
    $xml = simplexml_import_dom('http://something_from_a_url.xml');

    print_r($xml);
} else {
    exit('Failed to open xml file.');
}

when I execute this code it says failed to open, I fail to understand why..

simplexml_import_dom takes a DOM node, rather than a URL. You should use simplexml_load_file intead:

$xml = simplexml_load_file('http://something_from_a_url.xml');
print_r($xml);
