我甚至不明白的代碼，但我的想法，當我試圖發佈數據網絡它不工作，我不知道什麼是錯發送使用Arduino的GSM模塊的數據網絡與它我正在獲取網絡內容，但我不能發佈數據到網絡我試過既得到和發佈方法非他們給我帶來好運使用GPRS

我使用了相同的代碼，它工作。我只是想要你輸入相同的數據。你可以解釋一下你在上面代碼中使用的webhost的url。 – Billa

你的http請求有一些錯誤 – Billa

你在你的代碼中提出的http請求有一些錯誤。你不能像你那樣從arduino請求。

當使用000webhost數據庫時，最好的辦法就是利用PHP。你可以通過選擇文件管理器上傳PHP文件，然後選擇「現在上傳文件」。在那裏有一個名爲「public_html」的文件夾，它是PHP代碼將被上傳。

現在就在這裏做你想做的事情。你想創建一個PHP代碼，當php代碼的URL被請求時，它將執行數據庫的插入操作。然後你可以從arduino請求這個鏈接進行插入。

的PHP代碼是（請在代碼中所提供的地點提供您的用戶名，密碼，DBNAME，表名，字段名，並上傳它，因爲我上面說的）：

<?php 
$servername = "localhost"; 
$username = "provide your username here"; 
$password = "password here"; 
$dbname = "database name here"; 

// Create connection 
$conn = mysqli_connect($servername, $username, $password, $dbname); 
// Check connection 
if (!$conn) { 
    die("Connection failed: " . mysqli_connect_error()); 
} 



$sql = "INSERT INTO table_name (column_name) VALUES ('".mysqli_real_escape_string($conn,$_GET['sensor1'])."')"; 

if (mysqli_query($conn, $sql)) { 
    echo "New record created successfully"; 
} else { 
    echo "Error: " . $sql . "<br>" . mysqli_error($conn); 
} 

mysqli_close($conn); 
?>

獲取的URL上傳的PHP代碼（右鍵單擊上傳的文件並單擊查看，然後在瀏覽器中複製URL）。你可以在你的Arduino草圖中使用它。

你的arduino代碼應該看起來像（這個草圖中的URL不完整，取而代之的是我上面說的[http://afridiofkh.000webhostapp.com/phpfilename.php這是一個要被替換的東西。從http開始直到標記被替換]）：

這將執行插入操作，因爲您需要.PHP很容易，因爲它可以用來擴展操作。

試試這個。告訴我它是否有效，或者你是否面臨任何問題。 – Billa

今晚我會嘗試這一個，當我得到免費的感謝您的回覆 –

@Hazrat Bilal你試過嗎？ – Billa
