# Changing the max_input_vars directive in PHP scripts

This article describes how to change the maximum number of input variables allowed for PHP scripts by using the **max\_input\_vars** directive in a *php.ini* file.

  **Important**

  The information in this article only applies to certain types of hosting accounts. To determine whether or not the information below applies to your account, please see [this article](/docs/changing-php-settings-and-versions).

  📘 Note

  This article assumes that you have already set up a custom *php.ini* file on your web site. If you have not already set up a custom *php.ini* file, please read [this article](/docs/custom-php-ini-files) first.
</Warning>

## Using the max\_input\_vars directive

PHP obtains input variables from HTML forms (through GET and POST requests), as well as from any cookies enabled on a page. By default, the maximum number of input variables allowed for PHP scripts is set to 1000. You can change this amount by setting the **max\_input\_vars** directive in a *php.ini* file.

To change the maximum number of input variables allowed, use a text editor to add the **max\_input\_vars** directive to your *php.ini* file. For example, to set the maximum number of input variables to 1500, add the following setting:

```
max_input_vars = 1500
```

<Tip>
  To verify the current value of the **max\_input\_vars** directive and other directives, you can use the **phpinfo()** function. For more information, please see [this article](/docs/view-php-settings).
