How to add additional PHP directives for a domain in Plesk using command line?

Connect to the server via SSH

Create the file with all additional settings that will be applied to the domain (vi can be used or any other text editor, but this simple example shows single-line configuration file).
For example, it is required to add the directive 'sendmail_path = "/dev/null"':

# echo 'sendmail_path = "/dev/null"' > nomail.ini # this directive disables sending mail via PHP

Note: any directive, which is valid in php.ini can be specified, using the same format as in php.ini .

Apply the settings via the command:

# plesk bin site --update-php-settings example.com -additional-settings nomail.ini

It will give the same effect as if the contents of the specified file were copied to the Domains > example.com > PHP Settings > Additional configuration directives box in Plesk web GUI.

Note: Each time this command is run, the previous settings will be overwritten.
