PHP $ _POST获取数据数组 [英] PHP $_POST get data array

问题描述

我正在尝试使用相同的名称创建多个文本框.
这是我的代码.

I'm trying to do a multiple textbox with the same names.
Here is my code.

HTML

Email 1:<input name="email" type="text"><br>
Email 2:<input name="email" type="text"><br>
Email 3:<input name="email" type="text"><br>


PHP

$email = $_POST['email'];
echo $email;

我想得到这样的结果:

email1 @ email.com，email2 @ email.com，email3 @ email.com

我怎样才能做到这一点?有可能吗?

I wanted to have a results like this:

[e-mail], [e-mail], [e-mail]

How can I do that? is that possible?

推荐答案

在元素名称中使用[]

Email 1:<input name="email[]" type="text"><br>
Email 2:<input name="email[]" type="text"><br>
Email 3:<input name="email[]" type="text"><br>

将在PHP端返回一个数组:

will return an array on the PHP end:

$email = $_POST['email'];   

您可以implode()以获得所需的结果:

you can implode() that to get the result you want:

echo implode(", ", $email); // Will output [e-mail], [e-mail] ...

在对它们进行任何处理之前，例如，不要忘记对它们进行消毒.序列化数组或将它们插入数据库！仅仅因为它们位于数组中并不意味着它们是安全的.

Don't forget to sanitize these values before doing anything with them, e.g. serializing the array or inserting them into a database! Just because they're in an array doesn't mean they are safe.
