我想尝试弄清楚如何获取从Yelp Business API 2.0输出的数据,并实际选择我想要回显的位,添加样式,等等。

以下是基本查询:

<?php
        require_once ('lib/OAuth.php');

        $unsigned_url = "http://api.yelp.com/v2/business/the-waterboy-sacramento";

        // Set your keys here
        $consumer_key = 'mykey';
        $consumer_secret = 'mysecret';
        $token = 'mytoken';
        $token_secret = 'mytokensecret';

        $token = new OAuthToken($token, $token_secret);

        $consumer = new OAuthConsumer($consumer_key, $consumer_secret);

        $signature_method = new OAuthSignatureMethod_HMAC_SHA1();

        $oauthrequest = OAuthRequest::from_consumer_and_token($consumer, $token, 'GET', $unsigned_url);

        $oauthrequest->sign_request($signature_method, $consumer, $token);

        $signed_url = $oauthrequest->to_url();

        $ch = curl_init($signed_url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HEADER, 0);

        $data = curl_exec($ch);
        curl_close($ch);

        $response = json_decode($data);
        $json_string = file_get_contents($signed_url);
        $result = json_decode($json_string);

// Print it for debugging
echo '<pre>';
print_r($result);
echo '</pre>';

?>

在打印数据的区域中,如何修改此项,例如,仅返回 商家名称?或者只是商家地址?或两个项目,每个项目都包含在自己的div中?

是否有一个简单的方法,例如:

echo $business_name;
echo $business_address;

我基本上只是想弄清楚如何大量输出信息,这是基本的文本格式,默认情况下没有任何格式,实际上选择我要显示的内容,给每个位一个div它自己的类,所以我可以设计它并使它漂亮。

目前,print_r返回:

答案 0 :(得分:4)

这里有一个PHP对象,其中包含许多您可以自己检索的公共属性(stdClass是PHP可以创建对象的最简单的类)。对于名称,请尝试:

echo $result->name;

您可以从print_r输出中看到某些数据项是明智的嵌套。例如,如果您想要城市,则可以检索它:

echo $result->location->city;

现在,某些项目(例如地址)存储在对象中的数组中。要获取地址的第一行,请尝试以下操作:

echo $result->location->display_address[0];

值得阅读有关对象和数组的PHP手册,了解有关它们的作用以及如何访问它们的更多信息。以上只是基础知识,但会让你开始。

如果您想要整个地址,请考虑将display_address属性包装在implode中 - 这会将数组的元素与“粘合”字符串(例如逗号)连接在一起。这也是in the manual

最后,将数据“原始”渲染为HTML时要小心 - 如果此数据(您不自己控制)包含尖括号,则会破坏您的网站。因此,您需要在htmlspecialcharshtmlentities中包含上述所有内容,因此:

echo htmlentities($result->name);
