I've been working a loop that repeats incrementally, while displaying the kelvin and fahrenheit counterparts in a table. I'm using a do while loop to do so, however the function does not loop, and does not start on the correct number from the form.
The code I've done so far is:
<body>
<form action="" method="post">
Start temperature in degrees:<input type="text" name="start"></input><br />
End temperature in degrees:<input type="text" name="end"></input><br />
How should the list be incremented?:<input type="text" name="inc"></input><br />
<input type="submit" name="sub" value="Submit"></input><br />
</form>
<?php
$a = 1;
if ($_POST['sub']) {
$a = 0;
$start = $_POST['start'];
$end = $_POST['end'];
$inc = $_POST['inc'];
$x = $start;
do {
$x = $x + $inc;
$y = $x + 273;
$z = (1.8 * $x) + 32;
} while ($x >= $end);
}
?>
<?php
if ($a != 1) {
?>
<table>
<tr>
<th>Celsius</th>
<th>Kelvin</th>
<th>Fahrenheit</th>
</tr>
<tr>
<th>
<?php
echo "$x degrees <br />";
?>
</th>
<th>
<?php
echo "$y degrees <br />";
?>
</th>
<th>
<?php
echo "$z degrees <br />";
?>
</th>
</tr>
</table>
<?php
}
?>
</body>
Would I have to include while loops in the echo part of the table for it to loop? And how would I be able to have the loop start on the same number as the form?
