好的，我最后一个工作了，谢谢你们

这是它打印出来的警告，我看不出这里有什么错误

代码现在看起来像这样

<html>
<title>Search Records</title>
<head>
<body>
    <form name="" id="" method="post" action="search.php"/>
    <p> Enter Student name : <input type="text" name="fullname" id="fullname"/>
    <input type="submit" name="senda" value="Search Data" />

</form>

<?php
if(isset($_POST['senda'])){

    include 'mysqlconn.php';

    $con = new mysqli($host, $dbuser, $pass, $db) or die('Cannot Connect');
    $name = mysqli_real_escape_string($con,$_POST['fullname']);
    $sql = "SELECT * FROM scores WHERE fullname = '$name'";
    $result = mysqli_query($con,$sql)  or die("Error: ".mysqli_error($con));

    while($row = mysqli_fetch_array($result,MYSQLI_ASSOC))
    {

           printf("%s (%s)\n", $row['Fullname'] ." ". $row['studentNo'] ." ". $row['SubjectName'] ." ". $row['GPA'] ." ". $row['CGPA'] ." ". $row['SCORE']);
            mysqli_free_result($result);
    }
        mysqli_close($con);
    }

?>
</body>
</head>
</html>

我似乎看不出有什么不对劲，我到底做错了什么
