PHP fetch_array / sql没有排序值

SQL:

SELECT question,alt_1,alt_2,alt_3,alt_4 FROM questions WHERE id IN ('12','2','32','23')

PHP:

while ($questions = mysql_fetch_array($game)){
    echo "$questions[question]";
}

I want the rows to be printed in the order the values are sent to sql: 12 - 2 - 32 - 23.

But fetch_array/sql(?) seems to sort the values so the order becomes the following: 2 - 12 - 23 - 32 (starts with the lowest number..)

Is there any way to stop the array from being sorted by numbers!?

    USE FIND_IN_SET

    SELECT question,alt_1,alt_2,alt_3,alt_4 
    FROM questions 
    WHERE id IN ('12','2','32','23') 
    ORDER BY FIND_IN_SET(id, '12,2,32,23')
    

    Note FIND_IN_SET(id, '12,2,32,23') 12,2 without space

    FIND_IN_SET(field, 'val1,val2')
