为啥能这样写接收表单值呢

本帖最后由 phpcms2021 于 2015-03-24 10:56:05 编辑 post方式表单中有这样的数组:

看到别人写接值的时候用
POST['test']
那么问题来了,我的理解post中只能放变量,
比如
写成POST['test']
而第一种写法让人摸不着头脑,数组怎么能放进去呢,就算post能接数组,也不应该光秃秃的写一个test哈,还应该加一个[]即写成POST['test[]'],他这么写test,是个啥玩意呢,指代不明哈!而写成test[ ]才能表示是一个数组,况且test[ ]的形式也不能写成test来代替哈
还有点意思,这是怎么回事呢
------解决思路----------------------

对应 $_POST['test']


对应 $_POST['test']['abc']

这就没有问题了吧?

同名表单元素被解释为数组,是所有 web 语言都这样做的
唯有 php 加了一点约束
------解决思路----------------------
因為表示是一個數組。
