How do I restart php service after editing php.ini file on Linux operating systems?

In most cases you just need to restart web-server such as Apache / Nginx  depending on your system and software.

Execute the following command on your web-server:

Restart your Apache server by executing either of the command:

# /etc/init.d/apache2 restart

# apache2ctl restart

Restart your Nginx server by executing either of the command:

# /etc/init.d/nginx restart

# service nginx restart

# nginx -s reload

Restart your PHP-FAM Fastcgi by executing either of the command:

# /etc/init.d/php-fpm restart or # service php-fpm restart

# /etc/init.d/php5-fpm restart

# service php5-fpm restart (for php 5 fpm)

# /etc/init.d/php7.0-fpm restart

# service php7.0-fpm restart (for php 7 fpm)
