JSON只有一行正在打印

Question

目前，我正准备将AJAX响应提供给客户端。在这种情况下（示例），我在数据库中有两个值为tuper的值，但使用此代码时，它仅打印1 tuper值行。

下面是代码：

<?php 
    $con=mysqli_connect("localhost","root","","project"); 

    $user = isset($_POST['user']) ? $_POST['user'] : ''; 
    $pass = isset($_POST['pass']) ? $_POST['pass'] : ''; 


    function account($user, $pass) 
    { 
    global $con; 
    $result=mysqli_query($con,"SELECT * FROM account WHERE username='$user'"); 
    while($row=mysqli_fetch_array($result)) 
    { 
     $x = array('Username'=> $row['username'], 
        'Password' => $row['password']); 

     $accounts['Accounts'][]= $x; 
     return json_encode($accounts); 
    } 

} 
echo $acountList = account("tuper",$pass); 

?>

删除return while循环中。首先创建数组，然后将其返回。

function account($user, $pass) 
{ 
    global $con; 
    $data = array(); // setup container 
    $result = mysqli_query($con,"SELECT * FROM account WHERE username='$user'"); 
    while($row=mysqli_fetch_array($result)) { 
     $x = array(
      'Username'=> $row['username'], 
      'Password' => $row['password'] 
     ); 

     $data[] = $x; // push inside the container 
    } 

    $accounts['Accounts'] = $data; // after the loop is done 
    return json_encode($accounts); // then return it 
}
