How can a PHP beginner display the amount of a product sold today and increment it using a button on a web platform?

To display the amount of a product sold today and increment it using a button in PHP, you can store the sold amount in a database or a file. Retrieve the current sold amount, display it on the web platform, and increment it when the button is clicked by updating the stored value. 

<?php
// Retrieve the current sold amount from a file or database
$soldAmount = 100; // For example, retrieve from a database

// Display the current sold amount
echo "Amount sold today: " . $soldAmount;

// Increment the sold amount when the button is clicked
if(isset($_POST['increment'])) {
    $soldAmount++; // Increment the sold amount
    // Update the stored value in the database or file
    // For example, update the database with the new sold amount
}
?>

<form method="post">
    <input type="submit" name="increment" value="Increment Sold Amount">
</form>
