How can PHP be utilized to dynamically generate a user-friendly interface that allows customers to select available time slots for booking vehicles in the web application described in the forum thread?

To dynamically generate a user-friendly interface for selecting available time slots for booking vehicles in the web application, PHP can be used to query the database for available time slots and dynamically generate HTML elements such as radio buttons or dropdown menus for users to choose from. This can be achieved by using PHP to fetch the available time slots from the database and then dynamically generating the HTML elements based on the retrieved data.

// Assuming $availableTimeSlots is an array of available time slots fetched from the database
foreach ($availableTimeSlots as $timeSlot) {
    echo '<input type="radio" name="time_slot" value="' . $timeSlot . '">' . $timeSlot . '<br>';
}
