推荐答案

如果目的是仅将内容加载到应用程序中，则甚至不需要使用wget:

If the aim is to just load the contents inside your application, you don't even need to use wget:

$xmlData = file_get_contents('http://user:[e-mail]/file.xml');

请注意，如果 allow_url_fopen ，此功能将不起作用在php.ini或Web服务器配置(例如httpd.conf)中被禁用(默认情况下处于启用状态).

Note that this function will not work if allow_url_fopen is disabled (it's enabled by default) inside either php.ini or the web server configuration (e.g. httpd.conf).

如果您的主机明确禁用了它，或者您正在编写一个库，则建议使用 cURL 或抽象该库的库功能，例如枪口.

If your host explicitly disables it or if you're writing a library, it's advisable to either use cURL or a library that abstracts the functionality, such as Guzzle.

use GuzzleHttp\Client;

$client = new Client([
  'base_url' => 'http://example.com',
  'defaults' => [
    'auth'    => ['user', 'pass'],
]]);

$xmlData = $client->get('/file.xml');
