Answer 1

您没有保存mysqli_connect的结果并将其作为第一个参数传递给其他方法：

$db = mysqli_connect(...parameters omitted...);
mysqli_select_db($db, "id627165_mydb");
$result=mysqli_query($db, "select * from register where AadarNumber=$AadharNumber");

...等

Answer 2

用此替换您的代码并尝试检查：

<?php
session_start();
?>  
</head>
<body>

<div style="width:1350px; height:100px; background-image:url(images/tooplate_top.png); margin-top:10px">

mysqli_select_db（）正好需要2个参数
