How to Edit php.ini Files

PHP configurations are managed through the php.ini file, which can be edited to customize various PHP settings. The php.ini file is typically located in a specific directory depending on the PHP version being used. To find the path of the php.ini file, the command "php --ini" can be used in the terminal. For Nginx on Ubuntu, the php.ini file is usually located in /etc/php/[version]/fpm/php.ini. For OpenLiteSpeed on Ubuntu, the php.ini file is usually located in /usr/local/lsws/lsphp[version]/etc/php/[version]/litespeed/php.ini. To edit the php.ini file, a text editor like nano or vim can be used to open the file and modify the short_open_tag directive to enable short PHP tags. After making changes, the services need to be restarted to apply the changes, which includes restarting php-fpm and nginx for Nginx, and restarting lsws for OpenLiteSpeed. To verify the changes, a test PHP file can be created to check the short_open_tag value in the output. Editing the php.ini file requires attention to detail, and it is essential to ensure the correct path to the php.ini file and restart the appropriate services after making changes. This guide covers how to enable short PHP tags for both Nginx and OpenLiteSpeed on Ubuntu servers.
