How To Find php.ini? (Ubuntu LAMP on 18.04)

I’m trying to upload a large database to phpMyAdmin, and so need to adjust the values of upload_max_filesize, memory_limit and post_max_size in the php.ini configuration file. However I’m having trouble locating php.ini on my site…

I’ve trued mydomain/etc/php/7.2/cli/php.ini and mydomain/etc/php/7.1/apache2/php.ini both result in 404s. Where should php.ini be for an Ubuntu LAMP droplet on 18.04?

I’ll admit that this is a noob question, and I’m much more comfortable with FTP client GUIs. Any tips on modifying upload_max_filesize, memory_limit and post_max_size would also be appreciated. Right now just finding php.ini is the main obstacle.

Hi @alexanderCrab,

The best way to see which PHP.ini your website is looking at is using phpinfo. PHPinfo() is a PHP method which can be used in a file like so



Basically, what you need to do is create a file called info.php in your website’s directory.

touch info.php

Then open it and type in the method

nano info.php


Save and quit.

Now that you have the file open it in your browser. It will provide you with the loaded PHP.ini file from which you can actually start making the changes.
