This is a simple temperature conversion app that converts between Fahrenheit, Celsius and Kelvin.
We used PHP, HTML and CSS to build this app.
The following required functionality is completed:
- Convert at least 3 temperature types, for example Fahrenheit to Celcius, Celcius to Fahrenheit and Fahrenheit to Kelvin.
- Disallow incorrect data and provide feedback, for example, when a user inputs a string, the data is not processed and the user is informed of the mistake.
- Be built as nearly as possible to PSR-1 and PSR-2 standards.
The following optional features are implemented:
- Converts back and forth between all 3 types of temperatures, Fahrenheit, Celsius and Kelvin, back and forth (6 total conversions) and rounds the result to 2 decimal points.
Walkthrough of implemented features:
Challenges encountered while building the app:
Undefined Array Key Warning when using the isset() function and submitting an empty form. We solved this by creating a new variable and assigning it to the value of the array key using $_POST.
example:
if (isset($_POST['temp'])) {
$temp = $_POST['temp'];
} else {
$temp = '';
}
