HTML / Apache / PHP的标记中的标记的数量是否有限制？(Is there a limit to the number of tag in a tag for HTML/Apache

好的，这很奇怪。 我用mysql后端创建了一个简单的地址簿。 所以我添加了138行地址，一切都很好。 顺便说一句，我在输入文本中显示我的地址，以便任何用户都可以随时编辑它。 因此，当我按下提交按钮时，它会对所有138个行条目执行http发布并更新它们。 一切安好....

但是，在我尝试更新第139行输入的一天，它丢弃了最后一个输入输入并给出了错误！ 它给出了一个php运行时错误：“注意：未定义的索引：第24行的C：\ wamp \ www \ Dawah \ go.php中的lastN”。

顺便说一下LastN变量是使用$ _post ['lastN']获得的。

好像对可以在单个表单中发布的html输入标签的数量有限制！

我非常感兴趣。

以前有人遇到过这个吗？

Ok, this is weird. I have created a simple addressbook using php with mysql back end. So I added up to 138 rows of addresses, it's all fine. BTW I display my addresses in input texts so that any user can edit it anytime. So when I press a submit button, it perform http post on all 138 line entries and updates them. Everything is fine....

However, one fine day when I tried to update a 139th row input, it drops the last input input and give an ERROR! It gives a php run time error: "Notice: Undefined index: lastN in C:\wamp\www\Dawah\go.php on line 24".

btw the LastN variable is obtained using $_post['lastN'].

As if there is a limit to the number of html input tags that can be posted in a single form!

I am very much intrigued.

Has anybody come across this before?

有一个suhosin设置suhosin.request.max_vars，但这只是suhosin，而不是常规的PHP。

因为php 5.3.9 theres max_input_vars ，这似乎符合行为http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars

apache有限制请求大小的设置，但据我所知，它们以字节为单位，而不是变量数。 我想，apache会停止并发出abad请求，而不是像你看到的那样截断数据。

there's an suhosin setting suhosin.request.max_vars but that's only for suhosin, not regular php.

since php 5.3.9 theres max_input_vars, which seems to fit the behavior http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars

apache has settings to limit request size, but they're specified in bytes, not number of variables, as far as I know. I'd imagine apache would just stop and issue abad request instead of truncating the data like you're seeing.
