PHP使用兩個表創建樹形視圖

Question

我有兩個mysql表

  1. questions
  2. answers 

問題表中有問題，答案表中有與每個問題相關的答案，因此它具有級別

前

question 1 -> answer 1 -> question 2
           -> answer 2 -> question 3
           -> answer 3 -> question 4 -> answer 1 -> question 5
                                     -> answer 2 -> question 6
                                     -> answer 3 -> question 7
question 8 -> answer 1 -> question 9
           -> answer 2 -> question 10-> answer 1 ->question 12
                                        answer 2 ->question 13
           -> answer 3 -> question 11 

我需要以樹狀視圖顯示問題

前

question 1->question2
            question3
            question4->question 5
                       question 6
                       question 7
question 8->question 9
            question 10->question 12
                         question 13
            question 11

我的問題表字段是

id  qtype   qtext

我的答案表字段是

id  answer  quzid   targetquz

任何人都知道如何基於這兩個表使用php創建treeview。 非常感謝你。

Answer 1

希望我不會在這里誤解（不確定您是否有意要回答的問題，然后回答另一個沒有任何回答的問題）； 但總的來說，我會使用while循環。

while()
{ first level here
while()
{ second level here
while()
{ third level here
....
}
}
}
