论坛输入元素的数组值[关闭]

Question

I was under the impression that what ever is inserted into a <input type="text" name="something"> would be recieved as a string in PHP with $_POST['something'].

But now im running a tools to test my website and somehow $_POST['something'] can be an array.

How is that possible ?

Answer 1

If in your form you have inputs like <input name="something[]" ... /> you can have many of them or <select name="something[]" multiple ... />, etc.

$_POST['something'] would be an array.
