// Create Table header
echo "<tr>";
echo "<th>Temperature(F)</td>";
echo "<th>Temperature(C)</th>";
echo "</tr>";

// For loop to increament the temperature and print the table row
for($temp_in_fahrenheit = $temperature; $temp_in_fahrenheit < $temperature + 100; $temp_in_fahrenheit = $temp_in_fahrenheit + $increment) {
echo "<tr>";
//calculate temperature in celcius
$temp_in_celcius = ($temp_in_fahrenheit - 32) / 1.8;
//tempereature in fahrnheit
echo "<td>" . $i . "</td>";
//temperature in celcius
echo "<td>" . $temp_in_celcius . "</td>";
