我们会看到很多网站都可以实时的显示当时当地的天气,下面我来告诉你这种实时天气的做吧,利用google aip接口即可实现获取不同城市的天气并显示在自己网站上。

se.php,代码如下:

<?php

$city = $_GET['city'];

$data = createXml($city);

$xml = simplexml_load_string($data);

header("Content-type: text/xml");

echo $xml->asXML();

// 生成XML数据

function createXml($city)

{

    // Google 天气API

    $weather = simplexml_load_file("http://www.google.com/ig/api?weather={$city}");

    if(isset($weather->weather->forecast_conditions))

    {

        $low = f2c($weather->weather->forecast_conditions->low['data']);

        $high = f2c($weather->weather->forecast_conditions->high['data']);

        return "<weather>n<city>{$city}</city>n<low>{$low}</low>n<high>{$high}</high></weather>n";

    }

    else

    {

        return "<weather>n</weather>n";

    }

}

// 华氏度转摄氏度

function f2c($fahrenhite)

{

    return floor(($fahrenhite - 32) / 1.8);

}

客户端 c.php,代码如下:

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>天气查询</title>

</head>

<body>

<form method="post" action="">

<select name="city">

<option value="0">请选择</option>

<option value="beijing">北京</option>

<option value="shanghai">上海</option>

<option value="guangzhou">广州</option>

<option value="wuhan">武汉</option>

</select>

<input type="submit" />

</form>

<?php

if(!emptyempty($_POST['city']))

{

    $city = $_POST['city'];

    $xml = simplexml_load_file("http://127.0.0.1/rest/se.php?city={$city}");

    $html = "<p>City:{$xml->city}</p>n";

    $html .= "<p>Low:{$xml->low}</p>n";

    $html .= "<p>High:{$xml->high}</p>n";

    echo $html;

}

?>

</body>

</html>
