[1] => Array

[name] => aaa
[areaid] => 152
[listorder] => 10
)

)

Answer 1

foreach（三维 value）{
新二维=value；
}

Answer 2

使用foreach或for循环来重新构造一个二维数组。取三维数组中需要的元素。
具体语句取决于数组结构。建议贴出三维数组的结构。
===================
你想转成什么样的？ 只需要
[seller_credit] => Array
(
[total_num] => 36409
[level] => 12
[good_num] => 36091
[score] => 36042
)
)
这部分内容吗？
$new_a = array();
foreach($a as $aitem){
$new_a[] = $aitem['seller_credit'];

}
