How to make a link this is connected to database in php - php

Question

I am trying to make a php script which will get clients data from database in a table. the script works fine and is getting database fields correctly. Now i want to add a link beside every client info. The link should be like www.domain.com/check?clientid=$id&number=$phonenumber
How should i do this?
its a table and clients details are arranged in order. Please help me?
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT id, firstname, lastname, phonenumber, city, country, email FROM clients ORDER BY ID ASC";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<table><tr><th>ID</th><th>Name</th><th>Phone Number</th><th>Country</th><th>Email</th><th>Send SMS</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<tr><td>" . $row["id"]. "</td><td>" . $row["firstname"]. " " . $row["lastname"]. "</td><td>" . $row["phonenumber"]. "</td><td>" . $row["city"]. " "
. $row["country"]. "</td><td>" . $row["email"]. "</td></tr>";
}
echo "</table>";
} else {
echo "0 results";
}
$conn->close();
?>

I agree with Marcosh (in the comments), so that would give you this code (between the if(...) { and } else):
echo "<table><tr><th>ID</th><th>Name</th><th>Phone Number</th><th>Country</th><th>Email</th><th>Send SMS</th><th>Link to page</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<tr><td>" . $row["id"]. "</td><td>" . $row["firstname"]. " " . $row["lastname"]."</td><td>" . $row["phonenumber"]. "</td><td>" . $row["city"]. " ". $row["country"]. "</td><td>" . $row["email"]. "</td><td>Click me!</td></tr>";
}
echo "</table>";
Note 1: This will add a link with the text "Click me!". I think you may want to change that. You may also want to change the header (currently "Link to page")
Note 2: If you use php 5.5 or later, you can also use
echo "blablabla<td>{$row['id']}</td>etc..."
instead of
echo "blablabla<td>" . $row['id'] . "</td>etc..."

Thanks for help #ivo and i have learned how to get this thing done:
<td><form action='https://control.domain.com/api/sendhttp.php' method='GET'><input type='hidden' name='authkey' value='74685AiSz3dkBX5467773f'><input type='hidden' name='mobiles' value='" . $row['phonenumber'] .
