php 前台生成多维数组 后台批量添加

同一个地方绊倒两次，记录一下哈

1）前台表单，看 name

<div class="tab-pane row " id="tab-1" >
    <input type="hidden" name="data[1][Type]" value='' class="form-control" id="data[1][Type]">
    <input class="form-control" type="text" id="data[1][UnitPrice]" name="data[1][UnitPrice]" value="" placeholder="请输入单价" >
    <input class="form-control" type="text" id="data[1][Quantity]" name="data[1][Quantity]" value="" placeholder="请输入数量" >
    <input class="form-control" type="text" id="data[1][Name]" name="data[1][Name]" value="" placeholder="请输入费用名称" >
    <input class="form-control" type="text" id="data[1][Description]" name="data[1][Description]" value="" placeholder="请输入费用描述" >
</div>
<div class="tab-pane row " id="tab-2" >
    <input type="hidden" name="data[2][Type]" value='' class="form-control" id="data[2][Type]">
    <input class="form-control" type="text" id="data[2][UnitPrice]" name="data[2][UnitPrice]" value="" placeholder="请输入单价" >
    <input class="form-control" type="text" id="data[2][Quantity]" name="data[2][Quantity]" value="" placeholder="请输入数量" >
    <input class="form-control" type="text" id="data[2][Name]" name="data[2][Name]" value="" placeholder="请输入费用名称" >
    <input class="form-control" type="text" id="data[2][Description]" name="data[2][Description]" value="" placeholder="请输入费用描述" >
</div>

2）后台打印数据

Array
(
    [1] => Array
        (
            [Type] => 
            [UnitPrice] => 
            [Quantity] => 
            [Name] => 
            [Description] => 
        )
    [2] => Array
        (
            [Type] => 
            [UnitPrice] => 
            [Quantity] => 
            [Name] => 
            [Description] => 
        )
)
