Removing rows from table on website

[Tracomaster]

Any of you guys have knowledge about PHP and databases and stuff?

So I made this website and you can enter stuff into one table but some ass decided to spam it and I want to remove a couple of rows. 
Yet I have no clue where to put the delete query. I only have the website and the files in my filezilla. No mysqladmin or something...
help?

 

 

My code attached below for my php. I want to remove 1 or two certain rows from "klanten". This is within my html code.

 

<?php

 

$db = new mysqli('serverIP', 'username', 'password', 'username+db');

    if($db->connect_errno > 0){

    die('Unable to connect to database [' . $db->connect_error . ']');

    }  

 

     $sql = <<<SQL

    SELECT *

    FROM `Klanten`

    

SQL;

if(!$result = $db->query($sql)){

    die('There was an error running the query [' . $db->error . ']');

}

echo '<p><B>Deze hebben bij ons gekoopt</B></p>';

echo '<table>

    <tr>

    <th>KlantenID</th>

    <th>Namen</th>

    <th>Leeftijd</th>

    <th>Spammail</th>

    <th>Leefplaats</th>

    <th>RL Spammail</th>

    <th>Doekoepaasmethode</th>

    

     </tr>';

     

while($row = $result->fetch_assoc()){

    echo '<tr bgcolor = "#D94D3B">';

    echo '<td>' . $row['KlantenID'] . '</td>';

    echo '<td>' . $row['Klanten'] . '</td>';

    echo '<td>' . $row['Leeftijd'] . '</td>';

    echo '<td>' . $row['Email'] . '</td>';

    echo '<td>' . $row['Stad'] . '</td>';

    echo '<td>' . $row['Postcode'] . '</td>';

    echo '<td>' . $row['Betaalmethode'] . '</td>';

    

    echo '</tr>';

    

}    

 

 echo '</table>';

 

 $mysqli->close();

​

?>

If you don't have access to a database admin tool, you can create a new page (or add the code to the existing page) to simply remove the records you want... e.g.

 $sql = <<<SQL    DELETE FROM `Klanten` WHERE KlantenID = {ID NUMBER}SQL;$db->query($sql);
