PHP developerHP is a versatile server-side scripting language that powers a significant portion of the web. As a PHP developer, you may occasionally need to restart PHP to apply changes, resolve issues, or update the PHP configuration. In this guide, we will cover the process of restarting PHP on different platforms and for various web server setups.
Restarting PHP on Apache
If you’re using Apache with mod_php, you will need to restart the Apache web server to restart PHP. The method for restarting Apache varies depending on your operating system:
On Ubuntu/Debian:
Use the following command to restart Apache:
sudo systemctl restart apache2
On CentOS/RHEL:
Use the following command to restart Apache:
sudo systemctl restart httpd
On Windows:
Open the Services application, find the Apache service, right-click on it, and choose Restart.
Restarting PHP on Nginx
Nginx usually uses PHP-FPM (FastCGI Process Manager) to handle PHP requests. To restart PHP, you will need to restart the PHP-FPM service. The method for restarting PHP-FPM varies depending on your operating system:
On Ubuntu/Debian:
Use the following command to restart PHP-FPM:
sudo systemctl restart php-fpm
On CentOS/RHEL:
Use the following command to restart PHP-FPM:
sudo systemctl restart php-fpm
On Windows:
PHP-FPM is not officially supported on Windows. However, if you have installed PHP-FPM through a third-party package, restarting the PHP-FPM service may require restarting the respective package’s service.
Restarting PHP on LiteSpeed
LiteSpeed Web Server uses its native LSAPI to handle PHP requests. To restart PHP, you only need to restart the LiteSpeed Web Server. Use the following command to restart LiteSpeed:
sudo /usr/local/lsws/bin/lswsctrl restart
Conclusion
Restarting PHP is a relatively simple process once you know which web server you are using and the appropriate commands or steps for your operating system. This guide has outlined the necessary steps for restarting PHP on Apache, Nginx, and LiteSpeed web servers running on different platforms. With this knowledge, you can now confidently restart PHP whenever required.
