How to echo the results in PHP - php

Question

I need to be able to display the results of the submitted form with radio buttons. I want the ID to display with either of the results '1' or '2' from the radio button values.
i.e. ID: 13 - Value: 2
if the row id is set within name the radio buttons work fine but I'm not sure how to display the results from it
if the name of the radio button is set to 'ans' it links all radio buttons together, when I want them working per id
Please see my below code to explain a little better - I'm just not sure how to echo this
<?php
$sql = "SELECT * FROM 'tz_todo' ORDER BY 'position' ASC";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<table border='1' width='100%' bordercolor='#000000' style='border-collapse: collapse'><tr class='t1' bgcolor='#00204F'><th>
<font color='#FFFFFF'>ID</font></th><th><font color='#FFFFFF'>CHECK</font></th>
<th width='50'>
<font color='#FFFFFF'>OK</font></th><th width='50'><font color='#FFFFFF'>FAIL</font></th></tr>";
// output data of each row
while ($row = $result->fetch_assoc()) {
echo "<tr><td>
<p align='center'>" . $row["id"] . "</td><td>
<p align='center'>" . $row["text"] . "</td><td align='center' width='50'><input type='radio' name='" . $row["id"] . "' value='1'><br></td>
<td align='center' width='50'><input type='radio' name='" . $row["id"] . "' value='2'><br></td></tr>";
}
echo "</table><input type='submit' value='Submit' name='submit' class='buttons'> ";
} else {
echo "0 results";
}
$conn->close();
?>
</form>
<?php
if (isset($_POST['submit'])) {
echo("????????????????????????????????????");
}
?>
I've now amended it slightly and have it generating results but now the IDs aren't linked to the two radio buttons (1 and 2)
<?php
$sql = "SELECT * FROM `tz_todo` ORDER BY `position` ASC";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<table border='1' width='100%' bordercolor='#000000' style='border-collapse: collapse'><tr class='t1' bgcolor='#00204F'><th>
<font color='#FFFFFF'>ID</font></th><th><font color='#FFFFFF'>CHECK</font></th>
<th width='50'>
<font color='#FFFFFF'>OK</font></th><th width='50'><font color='#FFFFFF'>FAIL</font></th></tr>";
// output data of each row
while ($row = $result->fetch_assoc()) {
$rowid = $row["id"];
echo "<tr><td>
<p align='center'>" . $row["id"] . "</td><td>
<p align='center'>" . $row["text"] . "</td><td align='center' width='50'><input type='radio' name='ans' value='1'><br></td>
<td align='center' width='50'><input type='radio' name='ans' value='2'><br></td></tr>";
}
echo "</table><input type='submit' value='Submit' name='submit' class='buttons'> ";
} else {
echo "0 results";
}
$conn->close();
?>
</form>
<?php
if (isset($_POST['ans'])) {
$answer = $_POST['ans'];
if ($answer == "1") {
echo 'OK';
} elseif ($answer == "2") {
echo 'FAIL';
}
}
?>
Please let me know if you would like me to explain a little better or differently
Thanks,

Answer 1

I think I understand your problem. You should name the radio button this way for example
name='ans" . $row["id"] . "'
This way, radio buttons will work together for each row.

Answer 2

Instead of using the name field within the radio button, I've merged it all into the value field:
<input type='radio' name='radio' value='".$rowid." - 1'>
but then I have the problem that you can only select 1 radio button for all rows
