PHP查詢天氣預(yù)報的步驟：1、開通天氣預(yù)報接口服務(wù)，獲取接口請求Key；2、調(diào)用接口API發(fā)出請求查詢城市天氣；3、獲取返回的天氣相關(guān)信息，語法“$data = $result['result'];”，具體根據(jù)業(yè)務(wù)實際邏輯調(diào)整修改信息并輸出即可。

怎么利用PHP查未來多少天的天氣預(yù)報？下面本篇文章就來帶大家聊聊基于PHP的免費天氣預(yù)報接口查詢，希望對大家有所幫助。
1、開通接口
天氣預(yù)報接口服務(wù)使用的聚合數(shù)據(jù)提供的免費接口，每天可以100次免費調(diào)用?？梢酝ㄟ^ https://www.juhe.cn/docs/api/id/73?s=cpphpcn 注冊及開通。
2、通過PHP發(fā)起城市天氣查詢
<?php // 請求的接口URL $apiUrl = 'http://apis.juhe.cn/simpleWeather/query'; // 請求參數(shù) $params = [ 'city' => '蘇州', // 要查詢的城市 'key' => '您申請的接口調(diào)用Key' ]; $paramsString = http_build_query($params); // 發(fā)起接口網(wǎng)絡(luò)請求 $response = juheHttpRequest($apiUrl, $paramsString , 1); $result = json_decode($response, true); if ($result) { $errorCode = $result['error_code']; if ($errorCode == 0) { // 獲取返回的天氣相關(guān)信息，具體根據(jù)業(yè)務(wù)實際邏輯調(diào)整修改 $data = $result['result']; // 打印當(dāng)前實況天氣信息 echo "當(dāng)前城市：{$data["city"]}".PHP_EOL; echo "當(dāng)前溫度：{$data["realtime"]["temperature"]}".PHP_EOL; echo "當(dāng)前濕度：{$data["realtime"]["humidity"]}".PHP_EOL; echo "當(dāng)前天氣：{$data["realtime"]["info"]}".PHP_EOL; echo "當(dāng)前風(fēng)向：{$data["realtime"]["direct"]}".PHP_EOL; echo "當(dāng)前風(fēng)力：{$data["realtime"]["power"]}".PHP_EOL; echo "當(dāng)前空氣質(zhì)量：{$data["realtime"]["aqi"]}".PHP_EOL; } else { // 請求異常 echo "請求異常:{$errorCode}_{$result["reason"]}".PHP_EOL; } } else { // 可能網(wǎng)絡(luò)異常等問題，無法正常獲得相應(yīng)內(nèi)容，業(yè)務(wù)邏輯可自行修改 echo "請求異常".PHP_EOL; } /** * 發(fā)起網(wǎng)絡(luò)請求函數(shù) * @param $url 請求的URL * @param bool $params 請求的參數(shù)內(nèi)容 * @param int $ispost 是否POST請求 * @return bool|string 返回內(nèi)容 */ function juheHttpRequest($url, $params = false, $ispost = 0) { $httpInfo = array(); $ch = curl_init(); curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36'); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 3); curl_setopt($ch, CURLOPT_TIMEOUT, 12); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); if ($ispost) { curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $params); curl_setopt($ch, CURLOPT_URL, $url); } else { if ($params) { curl_setopt($ch, CURLOPT_URL, $url.'?'.$params); } else { curl_setopt($ch, CURLOPT_URL, $url); } } $response = curl_exec($ch); if ($response === FALSE) { // echo "cURL Error: ".curl_error($ch); return false; } $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); $httpInfo = array_merge($httpInfo, curl_getinfo($ch)); curl_close($ch); return $response; }

3、通過PHP發(fā)起生活指數(shù)查詢
// 請求的接口URL $apiUrl = 'http://apis.juhe.cn/simpleWeather/life'; // 請求參數(shù) $params = [ 'city' => '蘇州', // 要查詢的城市 'key' => '您申請的接口調(diào)用Key' ]; $paramsString = http_build_query($params); // 發(fā)起接口網(wǎng)絡(luò)請求 $response = juheHttpRequest($apiUrl, $paramsString , 1); $result = json_decode($response, true); if ($result) { $errorCode = $result['error_code']; if ($errorCode == 0) { // 獲取返回的天氣相關(guān)信息，具體根據(jù)業(yè)務(wù)實際邏輯調(diào)整修改 $data = $result['result']['life']; // 打印當(dāng)前實況天氣信息 echo "空調(diào)指數(shù)：{$data['kongtiao']['v']}，{$data['kongtiao']['des']}".PHP_EOL; echo "過敏指數(shù)：{$data['guomin']['v']}，{$data['guomin']['des']}".PHP_EOL; echo "舒適度指數(shù)：{$data['shushidu']['v']}，{$data['shushidu']['des']}".PHP_EOL; echo "穿衣指數(shù)：{$data['chuanyi']['v']}，{$data['chuanyi']['des']}".PHP_EOL; echo "釣魚指數(shù)：{$data['diaoyu']['v']}，{$data['diaoyu']['des']}".PHP_EOL; echo "感冒指數(shù)：{$data['ganmao']['v']}，{$data['ganmao']['des']}".PHP_EOL; echo "紫外線指數(shù)：{$data['ziwaixian']['v']}，{$data['ziwaixian']['des']}".PHP_EOL; echo "洗車指數(shù)：{$data['xiche']['v']}，{$data['xiche']['des']}".PHP_EOL; echo "運動指數(shù)：{$data['yundong']['v']}，{$data['yundong']['des']}".PHP_EOL; echo "帶傘指數(shù)：{$data['daisan']['v']}，{$data['daisan']['des']}".PHP_EOL; // ....... } else { // 請求異常 echo "請求異常:{$errorCode}_{$result["reason"]}".PHP_EOL; } } else { // 可能網(wǎng)絡(luò)異常等問題，無法正常獲得相應(yīng)內(nèi)容，業(yè)務(wù)邏輯可自行修改 echo "請求異常".PHP_EOL; }
