Edit php.ini file in ubuntu

Method 1

One way to find out exactly which

/etc/php/8.1/apache2/php.ini

/etc/php/8.1/apache2/php.ini

info.php

<?php
phpinfo();
?>

Load this file in your browser, press

/etc/php/8.1/apache2/php.ini

/etc/php/8.1/apache2/php.ini

/etc/php/8.1/apache2/php.ini

/etc/php/8.1/apache2/php.ini

/etc/php/8.1/apache2/php.ini

This will tell you the exact location of the php.ini file you want to edit.

Method 2

In Linux, run this command to locate the

/etc/php/8.1/apache2/php.ini

php -i | grep "Loaded Configuration File"

Or in Windows Command Line:

php -i | findstr /c:"Loaded Configuration File"

The result should be something like this:

Loaded Configuration File => /etc/php/8.1/cli/php.ini

In the above example, we can see that the PHP install is located in

/etc/php/8.1/apache2/php.ini

CLI

php -i | grep "Loaded Configuration File"

Apache

php -i | grep "Loaded Configuration File"

Nginx or Apache with PHP-FPM

php -i | grep "Loaded Configuration File"

Method 3

Using the

php -i | grep "Loaded Configuration File"

php -i | grep "Loaded Configuration File"

locate php.ini

You should see a list of php.ini files here. Try editing one of them and restarting you web server to see if makes the required changes.

php -i | grep "Loaded Configuration File"

php -i | grep "Loaded Configuration File"

php -i | grep "Loaded Configuration File"

To edit:

sudo nano /etc/php/8.1/apache2/php.ini

However, if you are using PHP FPM, it may be located in 

php -i | grep "Loaded Configuration File"

php -i | grep "Loaded Configuration File"

php -i | grep "Loaded Configuration File"

php -i | grep "Loaded Configuration File"

To edit:

sudo nano /etc/php/8.1/fpm/php.ini

To save file and exit, press 

/etc/php/8.1/apache2/php.ini

php -i | findstr /c:"Loaded Configuration File"

php -i | findstr /c:"Loaded Configuration File"

sudo systemctl restart apache2

If you are using PHP-FPM, you must restart that service. Replace
