PHP interview question: These five coupons are 50, 40, 30, 20, 1. The order amount is X yuan. How many coupons can be returned using a method?

First of all, I excluded the order amount that was not an integer because the interviewer only gave me 7 minutes.

mou(99);//Call the following method here

function mou($x){

$array = array{50,40,30,20,1};

$temp = 0 ;

$j = $x ;

for($i=0;$

{

$temp = $temp+foor($j/$array [$i]);

$j = $j%$array[$i];

}

echo "A total of ". $temp." coupons";

return $temp;

}

?>

This method is simply used to find a model. I hope some experts can give me a better method. Just reply directly
