Very often in phpmyadmin and php at large, there is need to increase the size of uploaded files. By default, php allows 2M. Here is a solution we derived at Kingline Press Uganda for Website and software developers

Although most tutorials on forums show that you only change these 2 variables,

post_max_size = 128M
upload_max_filesize = 64M

this is WRONG!

 

Here  is what to do

1- put  phpinfo();  function in a new php file and save that file on your server

2- run the file in your browser and locate “loaded configuration file” as shown below

3- open that file in an editor (sublime for me). change the following 3 lines

post_max_size = 128M
upload_max_filesize = 64M

This is the line with the problem. it is the culprit!
error_reporting : E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED

Change it to
error_reporting : E_ALL

Save php.ini

Find out php service name
systemctl list-unit-files | grep php

Restart php service
sudo service php7.0-fpm restart

Restart apache2 service
sudo service apache2 restart

Run phpinfo(); file in browser again to locate upload size

upload_max_filesize

200M
