3d Printer Energy Cost Calculator

To create a PHP code with an input form for calculating the total printer energy costs per day based on the provided formula, you can follow these steps:

  1. Create an HTML form with input fields for each of the variables (C, V, I, t, E, n).
  2. Use PHP to process the form data and calculate the energy cost.
  3. Display the result to the user.

Here's a sample PHP code with an input form:

<!DOCTYPE html>
    <title>Printer Energy Cost Calculator</title>
    <h1>Printer Energy Cost Calculator</h1>
    <form method="post" action="">
        <label for="V">AC Voltage (V):</label>
        <input type="number" name="V" required><br>

        <label for="I">Average current draw during print (Amps):</label>
        <input type="number" name="I" required><br>

        <label for="t">Time printers are running per day (Hours/day):</label>
        <input type="number" name="t" required><br>

        <label for="E">Energy cost from utility ($/kWh):</label>
        <input type="number" name="E" required><br>

        <label for="n">Number of printers:</label>
        <input type="number" name="n" required><br>

        <input type="submit" name="calculate" value="Calculate">

    // Check if the form is submitted
    if (isset($_POST['calculate'])) {
        // Get input values from the form
        $V = $_POST['V'];
        $I = $_POST['I'];
        $t = $_POST['t'];
        $E = $_POST['E'];
        $n = $_POST['n'];

        // Calculate the total printer energy costs per day
        $C = ($V * $I / 1000) * $t * $E * $n;

        // Display the result
        echo "<p>Total printer energy costs per day: $C $/day</p>";
