如何从数据库中的数据打印列表

Question

我想显示表格中显示的这些点的列表。

folio_mainPoint_bulletPoint_table
idFolio   idMainPoint   idBulletPoint
8         13            14
8         13            15
8         14            16
8         15            17
8         15            18
8         15            19

这些是我的表格：

folioTable 
idFolio folio
8       123

mainPointTable
idMainPoint mainPoint
13          Animals
13          Animals
14          Flowers
15          Insects
15          Insects
15          Insects

bulletPointTable
idBulletPoint bulletPoint
14            Dog
15            Cat
16            Rose
17            Ant
18            Grasshopper
19            Fly
20            ladybug

输出应为：

Folio 123

Animals
 1. Dog
 2. Cat

Flowers
 1. Rose

Insects
 1. Grasshopper
 2. Fly
 3. ladybug

我陷入困境，因为我一直在循环数据而不能打印出只有与idFolio为8的作品集相关的数据列表。这是我到目前为止的代码：

$sql = mysqli_query(" SELECT * FROM folio_mainPoint_bulletPoint_table where idFolio='8' ") or die(mysql_error());

while($row = mysqli_fetch_array( $sql )) {

echo  $folio = $row['idFolio'];
$idBulletPoint = $row['idBulletPoint '];

$sql2 = mysql_query("SELECT bulletPoint FROM bulletPointTable where idBulletPoint ='$idBulletPoint' ");
   while($row = mysqli_fetch_array( $sql2 )){

   }

}

Answer 1

试试此代码.. mysql_fetch_assoc()

    $sql = mysql_query("SELECT * FROM folio_mainPoint_bulletPoint_table where idFolio='8'") or die(mysql_error());

    while($row = mysql_fetch_assoc( $sql )) {

    echo  $folio = $row['idFolio'];
    $idBulletPoint = $row['idBulletPoint '];
    $sql2 = mysql_query("SELECT bulletPoint FROM bulletPointTable where idBulletPoint ='$idBulletPoint' ");
       while($row1 = mysql_fetch_assoc( $sql2 )){
   echo $row['column_name'];
       }

    }

Answer 2

while（$ result = mysql_fetch_assoc（$ sql））{
