{
    die("Database Connection Failed" . mysql_error());
}
$select_db = mysql_select_db( "emp",$connection);

{
    die("Database Selection Failed" . mysql_error());
}
    $sql = "SELECT * FROM venu ";     
    $result = mysql_query($sql) or die(mysql_error());
    ?>
    <table border="2" style= " margin: 0 auto;" id="myTable">
      <thead>
        <tr>
          <th>name</th>
          <th>id</th>
          <th>rollnumber</th>
          <th>address</th>
          <th>phonenumber</th>
        </tr>
      </thead>
      <tbody>
      <?php
            while($row = mysql_fetch_array($result))
            {
              echo "<tr>";
                echo "<td>" . $row['name'] . "</td>";
                echo "<td>" . $row['id'] . "</td>";
                echo "<td>" . $row['rollnumber'] . "</td>";
                echo "<td>" . $row['address'] . "</td>";
                echo "<td>" . $row['phonenumber'] . "</td>";
               echo "<td><form action='delete.php' method='POST'><input type='hidden'  value='".$row["address"]."'/><input type='submit' name='submit-btn' value='delete' /></form></td></tr>";
                echo "</tr>";


            }
            ?>
            </tbody>
            </table>
    </body>
    </html>

    In your html view page some change echo "<td><a href='delete.php?did=".$row['id']."'>Delete</a></td>"; like bellow: 

    <?php
while($row = mysql_fetch_array($result))
{
    echo "<tr>";
        echo "<td>" . $row['name'] . "</td>";
        echo "<td>" . $row['id'] . "</td>";
        echo "<td>" . $row['rollnumber'] . "</td>";
        echo "<td>" . $row['address'] . "</td>";
        echo "<td>" . $row['phonenumber'] . "</td>";
        echo "<td><a href='delete.php?did=".$row['id']."'>Delete</a></td>";
    echo "</tr>";
}
?>

    PHP delete code :

    <?php
if(isset($_GET['did'])) {
    $delete_id = mysql_real_escape_string($_GET['did']);
    $sql = mysql_query("DELETE FROM venu WHERE id = '".$delete_id."'");
    if($sql) {
        echo "<br/><br/><span>deleted successfully...!!</span>";
    } else {
        echo "ERROR";
    }
}
?>

    Note : Please avoid mysql_* because mysql_* has beed removed from PHP 7. Please use mysqli or PDO.

    More details about of PDO connection http://php.net/manual/en/pdo.connections.php

    And more details about of mysqli http://php.net/manual/en/mysqli.query.php
