PHP max_input_vars

PHP max_input_vars

提问by user39653

I'm getting a max_input_varserror message.

我收到一条max_input_vars错误消息。

I understand there's a php.inisetting that can change this starting with version 5.3.9 however, I'm running version 5.1.6.

我知道有一个php.ini设置可以从 5.3.9 版开始更改此设置，但是，我运行的是 5.1.6 版。

When I view the configuration information for my 5.1.6 server it shows max_input_varsvalue is 1000.

当我查看 5.1.6 服务器的配置信息时，它显示max_input_vars值为 1000。

My question is: Even though I'm running 5.1.6, I see this setting from phpinfo()but it's not in the php.inifile. Does this mean that the value is hard coded in this version of PHP and can't be changed?

我的问题是：即使我运行的是 5.1.6，我也看到了这个设置，phpinfo()但它不在php.ini文件中。这是否意味着该值在此版本的 PHP 中是硬编码的并且无法更改？

You can add it to php.ini and it should work - just tested it on PHP 5.3.6.

您可以将它添加到 php.ini 并且它应该可以工作 - 刚刚在 PHP 5.3.6 上对其进行了测试。

Reference on PHP net:

PHP网上参考：

http://php.net/manual/en/info.configuration.php#ini.max-input-vars

http://php.net/manual/en/info.configuration.php#ini.max-input-vars

Please note, you cannot set this directive in run-time with function ini_set(name, newValue), e.g.

请注意，您不能在运行时使用 function 设置此指令ini_set(name, newValue)，例如

ini_set('max_input_vars', 3000);

It will not work.

不起作用。

As explained in documentation, this directive may only be set per directory scope, which means via .htaccess file, httpd.conf or .user.ini (since PHP 5.3).

如文档中所述，此指令只能按目录范围设置，这意味着通过 .htaccess 文件、httpd.conf 或 .user.ini（自 PHP 5.3 起）。

See http://php.net/manual/en/configuration.changes.modes.php

见http://php.net/manual/en/configuration.changes.modes.php

Adding the directive into php.ini or placing following lines into .htaccess will work:

将指令添加到 php.ini 或将以下行放入 .htaccess 将起作用：

php_value max_input_vars 3000
php_value suhosin.get.max_vars 3000
php_value suhosin.post.max_vars 3000
php_value suhosin.request.max_vars 3000

Have just attempted this fix with 5.3.3 and there's no change. Googling around I found this web page http://anothersysadmin.wordpress.com/2012/02/16/php-5-3-max_input_vars-and-big-forms/detailing other settings which need changing if your server uses the Suhosin patchwhich Apache under Debian does.

刚刚在 5.3.3 中尝试了此修复程序，但没有任何变化。谷歌搜索我发现这个网页http://anothersysadmin.wordpress.com/2012/02/16/php-5-3-max_input_vars-and-big-forms/详细说明了如果您的服务器使用 Suhosin 补丁需要更改的其他设置Debian 下的 Apache 是做什么的。

The site explains:

该网站解释说：

So, if you want to increase this number to, say, 3000 from the default number which is 1000, you have to put in your php.ini these lines:

max_input_vars = 3000 suhosin.post.max_vars = 3000 suhosin.request.max_vars = 3000

因此，如果您想将此数字从默认数字 1000 增加到 3000，则必须在 php.ini 中添加以下几行：

max_input_vars = 3000 suhosin.post.max_vars = 3000 suhosin.request.max_vars = 3000

I tested it (added settings to php.ini both in /etc/php5/apache2 and /etc/php5/cli, and restarted Apache successfully) but still no max_input_vars variable in phpinfo.

我测试了它（在/etc/php5/apache2和/etc/php5/cli中向php.ini添加了设置，并成功重新启动了Apache）但phpinfo中仍然没有max_input_vars变量。

A few sites point to PHP 5.3.9 as the first PHP version in which this change will take, so my fault for not RTM properly in the first place, although I'm interested to see people reporting it working in version above 5.3.3 but below 5.3.9.

一些站点指出 PHP 5.3.9 作为此更改将采用的第一个 PHP 版本，所以我的错首先是没有正确 RTM，尽管我有兴趣看到人们报告它在 5.3.3 以上的版本中工作但低于 5.3.9。

You need to uncomment max_input_vars value in php.ini file and increase it (exp. 2000), also dont forget to restart your server this will help for 99,99%.

您需要在 php.ini 文件中取消注释 max_input_vars 值并增加它（exp. 2000），也不要忘记重新启动您的服务器，这将有助于 99,99%。

It's 2018 now.And I just got stuck on this problem when I must send a request that exceeds the max_input_vars. And I came up with a solution that newie like me forgot to restart php fpm service after changing the max_input_varsparam. because I only tried to restart apache2service, but not php fpm

现在是 2018 年。当我必须发送超过max_input_vars. 我想出了一个解决方案，像我这样的新手在更改max_input_vars参数后忘记重新启动 php fpm 服务。因为我只尝试重启apache2服务，而不是 php fpm

1. uncomment code at /etc/php/7.0/fpm/php.iniand set number as you wish
   max_input_vars = 4000
2. restart php fpm service, as I use php 7. Therefore,
   sudo service php7.0-fpm restart
   

1. 取消注释代码/etc/php/7.0/fpm/php.ini并根据需要设置数字
   max_input_vars = 4000
2. 重新启动 php fpm 服务，因为我使用的是 php 7。因此，
   sudo service php7.0-fpm restart
   

Hope it helps
Tested on Debian Stretch, php7.0

Use of this directive mitigates the possibility of denial of service attacks which use hash collisions. If there are more input variables than specified by this directive, an E_WARNING is issued, and further input variables are truncated from the request.

使用此指令可以减少使用哈希冲突的拒绝服务攻击的可能性。如果输入变量多于此指令指定的数量，则会发出 E_WARNING，并从请求中截断更多输入变量。

I can suggest not to extend the default value which is 1000 and extend the application functionality by serialising the request or send the request by blocks. Otherwise, you can extend this to configuration needed.

我可以建议不要扩展默认值 1000 并通过序列化请求或按块发送请求来扩展应用程序功能。否则，您可以将其扩展到所需的配置。

It definitely needs to set up in the php.ini

肯定需要在php.ini中设置

Note that you must put this in the file ".user.ini" in Centos7 rather than "php.ini" which used to work in Centos6. You can put ".user.ini" in any subdirectory in order to affect only that directory.

请注意，您必须将其放在 Centos7 中的“.user.ini”文件中，而不是在 Centos6 中使用的“php.ini”文件中。您可以将“.user.ini”放在任何子目录中，以便仅影响该目录。

.user.ini :

.user.ini :

max_input_vars = 3000

Tested on Centos7 and PHP 5.6.33.

Just had the same problem adding menu items to Wordpress. I am using Wordpress 4.9.9 on Ubuntu 18.04, PHP 7.0. I simply uncommented the following line and increased it to 1500 in /etc/php/7.0/apache2/php.ini

刚刚将菜单项添加到 Wordpress 时遇到了同样的问题。我在 Ubuntu 18.04、PHP 7.0 上使用 Wordpress 4.9.9。我只是取消了以下行的注释并将其增加到 1500/etc/php/7.0/apache2/php.ini

; How many GET/POST/COOKIE input variables may be accepted<br>
max_input_vars = 1500

Then used the following to effect the change:

然后使用以下内容来实现更改：

sudo apache2ctl configtest  #(if it does not return ok Apache will not start)
sudo service apache2 reload

Hope that helps.

希望有帮助。
