PHP的printf函数在旅游预订系统中可以用于格式化输出信息,例如显示酒店、航班、景点等详细信息。以下是一些可能的应用场景:
$hotel = array(
'name' => 'Hotel Example',
'address' => '123 Example St',
'rating' => 4.5,
'price' => 150.00
);
printf("Hotel Name: %s\n", $hotel['name']);
printf("Address: %s\n", $hotel['address']);
printf("Rating: %.1f\n", $hotel['rating']);
printf("Price: $%.2f\n", $hotel['price']);
$flight = array(
'flight_number' => 'AB123',
'departure_time' => '10:00',
'arrival_time' => '14:30',
'airline' => 'Example Airlines'
);
printf("Flight Number: %s\n", $flight['flight_number']);
printf("Departure Time: %s\n", $flight['departure_time']);
printf("Arrival Time: %s\n", $flight['arrival_time']);
printf("Airline: %s\n", $flight['airline']);
$attraction = array(
'name' => 'Example Attraction',
'address' => '456 Example Rd',
'opening_hours' => '9:00 - 17:00',
'ticket_price' => 20.00
);
printf("Attraction Name: %s\n", $attraction['name']);
printf("Address: %s\n", $attraction['address']);
printf("Opening Hours: %s\n", $attraction['opening_hours']);
printf("Ticket Price: $%.2f\n", $attraction['ticket_price']);
这些只是printf函数在旅游预订系统中的一些简单应用示例。在实际开发中,你可能需要根据具体需求来格式化输出更复杂的信息。
