Reference on PHP net:

<a href="http://php.net/manual/en/info.configuration.php#ini.max-input-vars" rel="noreferrer">http://php.net/manual/en/info.configuration.php#ini.max-input-vars</a>

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

<pre><code>ini_set('max_input_vars', 3000);
</code></pre>

It will not work.

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).

See <a href="http://php.net/manual/en/configuration.changes.modes.php" rel="noreferrer">http://php.net/manual/en/configuration.changes.modes.php</a>

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

<pre><code>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
</code></pre>

blocks|key|588254|text|使用此指令可以减少使用散列冲突的拒绝服务攻击的可能性。如果输入变量比该指令指定的多，则发出E_WARNING，并从请求中截断更多的输入变量。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|588255|我可以建议不要扩展默认值1000，而是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。|588256|它肯定需要在php.ini中进行设置|588257|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

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.

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.

It definitely needs to set up in the php.ini

"PHP message: PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini.

This php configuration parameter max_input_vars will affect not only your GET / POST / COOKIES parameters it also controls your any Form Input.

To set or change its value follow the below steps.

1) check the existing setting / value by viewing it in your php.ini file
Locate php.ini file by using

<code>&lt;?php echo getinfo(); ?&gt;</code>

find below key: Loaded Configuration File : /etc/php/5.6/fpm/php.ini 

2) Open the php.ini file in editable mode and do search for max_input_vars
 This line may be commented in your existing default setting with default value of 1000 , So remove ; to uncomment it and Edit it with your suitable value e.g. 2500.

3) Save the file and Restart the Services of PHP by using below
<code>sudo service php5.6-fpm restart</code>

Similarly you can update any other similar PHP Configuration to your ease.

Just to complement. On a shared server using mod_suphp I was having the same issue.

Declaring 4 max_input_vars (suhosin included), didn't solved it, it just kept truncating on 1000 vars (default), and declaring "php_value max_input_vars 6000" on .htaccess threw error 500.

What solved it was to add the following on .htaccess, which applies the php.ini file recursively to that path

<pre><code>suPHP_ConfigPath /home/myuser/public_html
</code></pre>

I'm getting a <code>max_input_vars</code> error message. 

I understand there's a <code>php.ini</code> setting that can change this starting with version 5.3.9 however, I'm running version 5.1.6. 

When I view the configuration information for my 5.1.6 server it shows <code>max_input_vars</code> value is 1000. 

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

PHP max_input_vars

服务器

Ubuntu

我收到一条max_input_vars错误消息。我知道有一个php.ini设置可以从5.3.9版本开始改变这一点，但我运行的是5.1.6版本。当我查看我的5.1.6服务器的配置信息时，它显示max_input_vars value is 1000。我的问题是:即使我运行的是5.1.6，我在phpinfo()中看到了这个设置，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
