When I make any changes in php.ini located in /usr/local/lib on centos, the changes don't appear to be applied, for example, when I clear all the content of php.ini and restart Apache everything works fine...

I searched for php.ini and it is in one place in system... what's the problem? How can I fix this?

if you're unsure what php.ini is being used, create a new file in your webfolder, name it phpinfo.php for example , with the following content

<?php
phpinfo();
?>

then open the url in your browser (http://www.example.com/phpinfo.php). it will show the path to the php.ini being used.

when you have identified the correct file, make your desired changes, and be sure to remove the leading ; in case there is one to activate the setting.

restart apache and reload the phpinfo page, your changed setting should now show up. if it doesn't, make sure you don't have a .htaccess file in your webroot that overrides php settings.

You may want to read these threads:

hints:

  1. What is "Loaded Configuration File" in php_info output? -> check that you edit the correct ini-file.
  2. check for multiple occurences of your setting in the same file.
  3. Gryphius´s hint is not bad either: Uncomment the setting! (remove the leading ";")
  4. Check permissions on the ini file. The web server and php-cgi/php-fpm need read access.
  5. php 5 and later: Do not only restart the web server, but also the php-fpm service before testing.

If you are using apache you should know there are 2 ini files:

/etc/php/7.4/apache2/php.ini

and

/etc/php/7.4/cli/php.ini

You should change the one in /etc/php/7.4/apache2/php.ini

replace 7.4 with your php version

I found a very blatant error in my php.ini file which caused this very symptom, eg. some php.ini settings did not take effect..

As of php7.0, the # character is not a valid comment starter. Only ; is accepted. But still many editors, for example vim, show characters after "#" as comments so you may not recognise that a certain part of the php.ini file is not an ignorable comment.

In my case, the php.ini filed contained this:

# ""
max_input_vars = 3000

The max_input_vars = 3000 did not take effect because the previous line is not a comment. It has some side-effect which causes my next line to be ignored.

Changing it to 

; ""
max_input_vars = 3000

solved the problem.

Follow this:

Create a file inside your webroot naming it whatever you want. I usually prefer x.php

 # vim x.php

The contents of the file should be this:

<?php
phpinfo();
?>

Now open this file in your browser like this:

http://server_ip/x.php

This will show you the location of the php.ini your apache is using. Edit that php.ini and it will work.

cannot comment here yet, but: Does it work if you keep the changes and restart Apache?

If so, the reason is probably that PHP runs as an Apache module.
If you want changes to have effect without restarting the web server, use php-cgi instead.

This page explains installation and configuration; search the page for "as an Apache Module" or for "PHP 5 as a CGI Binary".
