Answer 1

To read two purchases of gasoline from different gas stations and calculate the cost per liter of gasoline in each station using PHP and the POST request method, you can create a form to get the input from the user and calculate the cost per liter based on the entered values.

Step-by-step explanation:

To solve this problem, you can use the PHP language and the POST request method to read the two purchases of gasoline and the number of liters for each purchase. Here's an example of how you can write the code:

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$gasStation1 = $_POST['gasStation1'];
$liters1 = $_POST['liters1'];
$gasStation2 = $_POST['gasStation2'];
$liters2 = $_POST['liters2'];

$costPerLiter1 = $gasStation1 / $liters1;
$costPerLiter2 = $gasStation2 / $liters2;

echo 'Cost per liter at Gas Station 1: ' . $costPerLiter1;
echo 'Cost per liter at Gas Station 2: ' . $costPerLiter2;
}
?>

To get the input from the user, you can create a form using the HTML <form> tag and set the method attribute to 'POST'. Then you can use the PHP $_POST superglobal to retrieve the values entered by the user in the form. Finally, you can calculate the cost per liter by dividing the total cost by the number of liters for each purchase.

The output will be displayed on the webpage after the form is submitted. It will show the cost per liter of gasoline at each gas station based on the input provided by the user.
