Modifying php.ini

If you need to modify the configuration file of your PHP instance, to a certain extent it is possible to do so.

Some parameters can’t be changed. The list of these unmodifiable parameters is below.

How to modify your php.ini

Access your instance with SFTP and download the file /lamp0/etc/php/php-custom.ini Locally edit the file, putting in the values you want to change. Values that remain unmodified will remain at the defaults.​ ​(See default phpinfo). When you are satisfied with your version of the file, upload it to your instance, replacing the original (lamp0/etc/php/php-custom.ini).

To make your changes effective, you need to reboot your instance.

Note

Alternatively you can modify the php-custom.ini file from within your instance’s Control Panel under the “Edit PHP Configuration” section.
