你想要的是:

curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);  

Zend有一个REST客户端和zend_http_client，我确信PEAR有某种包装器。 但是你自己做也很容易。

所以整个请求看起来是这样的:

$ch = curl_init($host);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml', $additionalHeaders));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadName);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$return = curl_exec($ch);
curl_close($ch);

Yahoo有一个使用PHP调用REST服务的教程:

让雅虎!使用PHP调用Web服务REST

我自己没有使用过，但雅虎就是雅虎，至少应该保证一定程度的质量。但是，它们似乎不包括PUT和DELETE请求。

另外，用户对curl_exec()和其他的贡献注释包含了很多好的信息。

市面上有多种REST框架。我强烈建议你看看Slim mini Framework for PHP 以下是其他一些公司的名单。

Michael Dowling的《Guzzle》便是一个不错的选择。除了优雅的接口、异步调用和符合PSR，它还使REST调用的身份验证头非常简单:

// Create a client with a base URL
$client = new GuzzleHttp\Client(['base_url' => 'http://myservices.io']);

// Send a request to http://myservices.io/status with basic authentication
$response = $client->get('/status', ['auth' => ['username', 'password']]);

去看医生。

你只需要指定CURLOPT_HTTPAUTH和CURLOPT_USERPWD选项:

$curlHandler = curl_init();

$userName = 'postman';
$password = 'password';

curl_setopt_array($curlHandler, [
    CURLOPT_URL => 'https://postman-echo.com/basic-auth',
    CURLOPT_RETURNTRANSFER => true,

    CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
    CURLOPT_USERPWD => $userName . ':' . $password,
]);

$response = curl_exec($curlHandler);
curl_close($curlHandler);

或者指定头文件:

$curlSecondHandler = curl_init();

curl_setopt_array($curlSecondHandler, [
    CURLOPT_URL => 'https://postman-echo.com/basic-auth',
    CURLOPT_RETURNTRANSFER => true,

    CURLOPT_HTTPHEADER => [
        'Authorization: Basic ' . base64_encode($userName . ':' . $password)
    ],
]);

$response = curl_exec($curlSecondHandler);
curl_close($curlSecondHandler);

狂饮的例子:

use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;

$userName = 'postman';
$password = 'password';

$httpClient = new Client();

$response = $httpClient->get(
    'https://postman-echo.com/basic-auth',
    [
        RequestOptions::AUTH => [$userName, $password]
    ]
);

print_r($response->getBody()->getContents());
