游客天气信息的PHP代码

您需要一个天气API。看看，API文档是可用的

使用cURL的PHP示例：

<?php
require_once('geoplugin.class.php');
$geoplugin = new geoPlugin();
// If we wanted to change the base currency, we would uncomment the following line
// $geoplugin->currency = 'EUR';

$geoplugin->locate();
echo "<p </span></p> </br>"; 
echo "<p style='text-align: center;'><span style='font-size: 50px; font-family: georgia,palatino; color: #202020 ;'> Your IP Address is {$geoplugin->ip} </span></p> </br>"; 
echo "<p style='text-align: center;'><span style='font-size: 16px; font-weight: bold; text-decoration: underline; font-family: georgia,palatino; color: #D67900;'> More Information About You </span></p>"; 
echo "<p style='text-align: center;'><span style='font-size: 13px; font-family: georgia,palatino; color: #686868;'> Your Country: {$geoplugin->countryName} | City: {$geoplugin->city} | Country Code: {$geoplugin->countryCode} | Longitudes: {$geoplugin->longitude} | Latitude: {$geoplugin->latitude} | Currency Code: {$geoplugin->currencyCode} | Currency Symbol: {$geoplugin->currencySymbol} </span>"; 
?>

以下是答案

<?php
    $City = "London"; //Assign the city
    $APIKey = "42esgfa4pfqp6zwgr4egjbph"; //Assign the API key
        $WeatherRequest = curl_init(); //make a new cURL request
        curl_setopt_array($WeatherRequest, array(
            CURLOPT_RETURNTRANSFER => 1,
            CURLOPT_URL => "http://api.worldweatheronline.com/free/v1/weather.ashx?q=".$City."&format=json&num_of_days=5&key=".$
        ));
        $Response = curl_exec($WeatherRequest); // execute the cURL request and get the reponse
        curl_close($WeatherRequest); // Close the request after we have received the response
        $JSON = json_decode($Response, true);
        //if using Celsius:
        echo($JSON["data"]["current_condition"]["temp_C"]);
        //if using fahrenheit:
        //echo($JSON["data"]["current_condition"]["temp_F"]);
?>

你在找气象服务吗？这可能会帮助你，我已经有一个关键，我需要把在网址。世界天气在线。com/free/v1/weather.ashx？q=“.$City.”&format=json&num_of_days=5&key=“$APIKey@Arun您的评论很难理解，但我认为您的意思是“我把API密钥放在哪里”-在我给您的示例中，替换变量“$APIKey”“使用您的API密钥。谢谢thomas u完美地回答了我的问题。@Arun请看如何接受答案，但是thomas我得到的结果很难理解。有没有办法单独测量温度？
