Locating php.ini

Your system may well have more than one PHP version / install. Even with the same version there can be different versions, e.g. cli and fpm

The best way to find out what version apache is using is to load a page with the following:

  phpinfo();
  die;

Edit php.ini

Creating a backup copy first

cp /etc/php/7.4/fpm/php.ini /etc/php/7.4/fpm/php-old.ini

Editing the file

sudo nano /etc/php/7.4/fpm/php.ini

Searching for text within file

CTRL+W
Enter your text, press return

To find the next occurrence use CTRL+W again and just press return

Specific values

upload_max_filesize – Found that apache restart didn’t update, server reboot caused new setting to load.

post_max_size – Found that apache restart didn’t update, server reboot caused new setting to load.
