php - 即使刷新页面，也要保持随机播放的值

Question

I made a quiz that generates a random answer at the end by using the shuffle() function. I want it to stay on the same answer and not to shuffle again.

My code:

<?php

//Array of cars
$answer = array(
"Mercedes", 
"Benz", 
"Honda", 
"Toyota", 
"Nissan", 
"Mazda", 
"Hyundai", 
"Ford", 
"Lexus", 
"Lamborghini", 
"Ferrari", 
"Porche", 
"Mitsubushi", 
"Scion", 
"Chrysler", 
"Jeep", 
"Masarati"
);

// Shuffle the order
shuffle($answer);

echo $answer[0];
?>

For example: if $answer was shuffled and generated "Mitsubushi" --- when I refresh the page it should stay "Mitsubushi" but what happens is that when the page is refreshed it reshuffles again.

So when I refresh the page, it echo's another thing do the shuffle() function.

Thanks in advance.

You are looking for sessions. You need to call session_start and store the value in $_SESSION.
