为什么$ _POST中的字符串不能包含点“."? [英] Why strings in $_POST can not contain a dot "."?

问题描述

基本上标题就是全部.我在页面上有一个隐藏的输入，我想在其中将名称设置为"some.major.uber.setting"

Basicaly the title say's it all. i had an hidden input on my page where i wanted to set the name to "some.major.uber.setting"

例如: <input type="hidden" name="some.major.uber.setting" value="dummy value" />

当我查看$ _POST数据时，它包含"some_major_uber_setting".谁能解释这种行为

and when i looked at the $_POST data it contained "some_major_uber_setting". Can anybody explain this behaviour

推荐答案

这可能与register_global = On时间有关. $ _GET/$ _ POST变量被转换为标准变量($ _GET ['foo']变为$ foo).变量名称不能包含点，因此它们在内部进行了转换.

That is probably a relict from register_global = On times. $_GET/$_POST variables were turned into standard variables ($_GET['foo'] became $foo). Variable names can't contain dots so they were internally converted.
