Configuring PHP via php.ini on Hosting

The PHP engine can be configured using a special file php.ini. This file contains various settings and their values.

There are various ways to change these values:

• You can edit the settings manually by opening the file in an editor. In this case, the settings are applied to all sites.
• You can change the settings via the .htaccess file. In this case, the settings are applied to a specific site.
• You can change the settings via a special PHP function ini_set. In this case, the settings are applied to a specific script.

On hosting, we do not have access to directly edit the php.ini file. However, the hosting control panel may have an interface for changing a limited number of parameters.

Also, the option with ini_set and the .htaccess file will work on hosting, but also in a limited way. We will study this in more detail in the following lessons.
