通過使用HTTP POST & GET方法，我可以獲得單個數據並且能夠使用MySQL數據庫插入多個數據。Android HTTP POST從MySQL數據庫中獲取多個值
現在我想從MySQL數據庫多個值，並將其顯示在Android上的TextView .... 我不知道如何選擇查詢存儲在陣列和Android的
得到這個數組值或者我必須使用JSON ..？
我的價值.php。
<?php
$con=mysqli_connect("localhost","arun","sachin11");
$db_select=mysqli_select_db($con,"Schoolapp");
if($db_select)
{
//echo "<br>db selected";
}
else
{
//echo "<br>db not exists";
}
//$ChildPassportname = $_GET['ChildPassportname'];
$query ="SELECT `Username`,`Password`,`Email`,`Gender` FROM `schooldb` WHERE ChildPassportName = 'arun2' ";
$result=mysqli_query($con,$query);
while($row = mysqli_fetch_array($result))
{
echo $row['Username'] . " " . $row['Password']. " " . $row['Email']. " " . $row['Gender'];
echo "<br>";
}
mysqli_close($con);
?>
