Can't change max_input_vars in PHP

I need to raise the max_input_vars value in php for a moodle installation. However when I change the value in my php.ini file the moodle web installer still prompts:

PHP setting max_input_vars must be at least 5000.

phpinfo() shows:

max_input_vars => 5000 => 5000

also editing the .htaccess file had no effect.

In PHP 8.1 trick is to find correct loded php.ini file for Web Server (Apache)

What I have found for Ubuntu and PHP 8.1 is that, command "php --ini" is showing loaded confirmation file for CLI not Apache2. See below image. enter image description here

So I have to find the php.ini file in same php 8.1 folder for Apache2 and set the max_input_vars to 5000 .

In my case it was the wrong php.ini file I edited. The comment from @JacobMulquin directly to the question and the answer from @RusselEngland helped me find that out.

I have a webserver (Ubuntu 22.04 LTS) running with multiple PHP versions as fpm, and therefore I had to edit the /etc/php/8.3/fpm/php.ini instead of the /etc/php/8.3/apache2/php.ini.

I thought this should be posted as an answer so others struggling with the same problem may find it faster.

I had the same error in Moodle installer on Fedora. After changing /etc/php.ini with

max_input_vars = 5000

error would not go away even after max_input_vars changed. Appears it is not enough to restart web server (apache in my case)

sudo systemctl restart httpd

also needed to

sudo systemctl restart php-fpm.service

Create a temporary php file in the Moodle directory with the following and run it via the browser (running php via the command line uses a different php ini file not the apache file)

<?php

phpinfo();

This will confirm which php ini file is being used, eg /etc/php/xx/apache2/php.ini

Also search the page for max_input_vars to see what the value is.

Master is the value in php.ini - if its not 5000 then the wrong php ini file has been edited, or you need to restart apache

Local is the value being used - if its different to the master value, then its been overwritten by apache

In which case, check .htaccess and the conf files in the apache directories eg etc/apache2/

If the local value is correct - 5000 - then its been changed by code in the Moodle directory somewhere. Maybe check config.php or search the code for max_input_vars
