php - FORM 和 POST 数组中 Checkboxes 的顺序是否相同？

Question

我有几个复选框，我正在尝试采用一种懒惰的方法将它们插入到数据库中。

所以我想知道，POST super 数组中的复选框数组 (checkboxes[]) 的顺序是否与它们在我的 html 页面中的顺序相同？

如果没有，那我就不再是一个懒惰的开发者了!

感谢您的帮助。

是的，参见 17.13.4 Form content types of the HTML 4 specification .对于 application/x-www-form-urlencoded :

The control names/values are listed in the order they appear in the document. The name is separated from the value by = and name/value pairs are separated from each other by &.

对于 multipart/form-data :

The parts are sent to the processing agent in the same order the corresponding controls appear in the document stream.

PHP 手册声明相同(参见 How do I create arrays in a HTML <form> ? ):

Specifying an arrays key is optional in HTML. If you do not specify the keys, the array gets filled in the order the elements appear in the form.
