Can't change max_input_vars limit in php.ini-CodePudding

I need to change PHP max_input_vars variable but after change in php.ini and server restart phpinfo shows old value all the time. This is what i do:

in phpinfo() i've got

...
Loaded Configuration File /etc/php.ini
...
max_input_vars  1000

from server CL I've edit /etc/php.ini and uncomment line with max_input_vars it looks like this:

...
max_input_vars = 5000
...

after this changes and restarting web server

systemctl restart httpd

phpinfo still shows max_input_vars as 1000 It looks like php use some other php.ini or values are overwritten because with other settings like max_execution_time is the same.

If i'm doing it wrong way? Is this possible that phpinfo shows different configuration file than the one used?

phpinfo output:

As you're using PHP-FPM, you need to check it's configs for overrides, typically in /etc/php-fpm/*.conf.

php_admin_value[max_input_vars] = XXX

After validating there are no overrides that affect your settings, restart the php-fpm service and as a best-practice also Apache.

systemctl restart php-fpm httpd

Restarting the PHP-FPM service is required because Apache passes requests to the running PHP instance(s) loaded into memory from the PHP-FPM service. As PHP is already loaded into memory by PHP-FPM, the PHP-FPM service needs to be restarted for PHP configuration changes to be applied.

Apache prior to PHP-FPM typically relied on starting the PHP process using the Apache mod_php, thereby requiring the restarting of the Apache service for configuration changes to be applied immediately, or until mod_php reloaded the PHP instance.

Based on your configuration, you should add additional PHP config settings to /etc/php.d/zzz-custom.ini instead of /etc/php.ini. PHP will load the config files in alphabetical order, resulting in the zzz-custom.ini file being loaded last and be used as the final values of the PHP settings.
Using the /etc/php.d/zzz-custom.ini file will also prevent the loss of your custom php.ini settings and the need to make extensive changes to the default /etc/php.ini file when updating PHP versions.
However, /etc/php-fpm/*.conf settings will take precedent over any /etc/php.d/*.ini configs.

If you find your existing PHP. ini, open the file and locate the following line of code (xx represents a number): max_input_vars = xx ; And set it to your desired limit. ...
