这里利用数组来做实例,有需要的要改成数据库查询然后再存到数据操作,实例代码如下:
<?php
$a = array(
'AAAAAA' => array(
'aaaaaa' => array(
'111111',
'222222',
'333333'
),
'bbbbbb' => array(
'111111',
'222222',
'333333'
),
'cccccc' => array(
'111111',
'222222',
'333333'
),
),
'BBBBBB' => array(
'aaaaaa' => array(
'111111',
'222222',
'333333'
),
'bbbbbb'=> array(
'111111',
'222222',
'333333'
),
'cccccc'=> array(
'111111',
'222222',
'333333'
),
),
'CCCCCC' => array(
'aaaaaa'=> array(
'111111',
'222222',
'333333'
),
'bbbbbb'=> array(
'111111',
'222222',
'333333'
),
'cccccc' => array(
'111111',
'222222',
'333333'
),
),
);
foreach ($a as $k=>$v){
echo $k."<br>";
// if(is_array($v)){
foreach($v as $key=>$val){
echo " ".$key."<br>";
// }
if(is_array($val)){
foreach($val as $kkk=>$vall){
echo " ".$vall."<br>";
}
}
}
echo "<br>";
}
