Hello guys,
PHP is an interpreted language designed to create dynamic web sites. PHP is integrated with the web server running on the server. In order to restart PHP, you need to restart the web server it is attached to. Means whenever you will make changes in php.ini file then you will have to restart the apache server service for it.
To restart apache server service run command as below.
Quote#/etc/init.d/httpd restart
OR
Quote#service httpd restart
Enjoy !!!
