我重新检查语法，我无法在加载的页面中查看href链接

I am trying to update the parameters the url can contain by giving a link in the loaded php, but i am not able to view the link itself, i can see the table being loaded but no the link in the loaded page, may be something silly, but please help me. I tried in all the browsers

<!Doctype html>
<table border="1" id="table">

    <p> <tr><th bgcolor="#9999FF">My repute</th>
    </p>
   </tr>
     
<?php
$c=$_GET['a'];
$d=$_GET['b'];
$tr=$_GET['j'];
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "repute system";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection_aborted(oid)
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT name,repute FROM teacher ";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
     
     if($c== $row['name'])
     {   
            echo "<tr><td Repute: >   " . $row["repute"]. "</tr></td>";
            $rep=$row['repute'];
     }
    }
} 
else {
    echo "0 results";
}
$some = "<a href = 'index.php?param=$tr&param1=$a&param2=$b'>Click here to go back</a>";
$conn->close();
?>
</table>
<a href="#"> <?php echo $some; ?> </a>
</html>

</div>

You have to fix your HTML first to solve the problem. When the HTML have problems some tags may not be rendered by the browser.

This line is very messy and wrong

<p> <tr><th bgcolor="#9999FF">My repute</th>
</p>
</tr>

You can fix it like this

<tr><th bgcolor="#9999FF"><p>My repute</p></th></tr>

This line:

"<tr><td Repute: >   " . $row["repute"]. "</tr></td>";

Become (fixed <tr><td>...</tr><td> in <tr><td>...</td><tr>):

"<tr><td>Repute: " . $row["repute"]. "</td></tr>";

Also you have to put your html inside body tag

<!DOCTYPE html>
<html>
    <head> </head>
    <body>
       <!-- Add here the CODE -->
    </body>
<html>
