Location of php.ini on Ubuntu 20.04 step by step instructions

  1. Create a file called phpinfo.php within your web-server’s root directory eg. /var/www/html/ with the following content: 
    <?php

// Show all information, defaults to INFO_ALL
phpinfo();

?>?
  2. Navigate your web browser to the URL location http://SERVER-HOST-OR-IP/phpinfo.php. Search the page for the loaded php.ini configuration file.

    3. Alternatively execute the following command to locate the loaded php.ini configuration file for the command line (cli) php command:

    php --ini | grep Loaded
Loaded Configuration File:         /etc/php/7.3/cli/php.ini

    Please, note that the above php.ini file location is used by phpcommand. For the Apache web-server the above path will translate to:

    /etc/php/7.3/apache2/php.ini

    For Nginx or Apache with PHP-FPM the path will most likely be:

    /etc/php/7.3/fpm/php.ini
