Using []in the element name
使用[]的元素名称
Email 1:<input name="email[]" type="text"><br>
Email 2:<input name="email[]" type="text"><br>
Email 3:<input name="email[]" type="text"><br>
will return an array on the PHP end:
将在 PHP 端返回一个数组：
$email = $_POST['email'];
you can implode()that to get the result you want:
你可以implode()得到你想要的结果：
echo implode(", ", $email); // Will output [email protected], [email protected] ...
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.
在对这些值做任何事情之前不要忘记清理它们，例如序列化数组或将它们插入到数据库中！仅仅因为它们在一个数组中并不意味着它们是安全的。
