I know MK OS is not usual suppots a PHP server because some web pages with PHP code can be too heavy. However, I want to include some PHP lines in order to improve the security.
Is there any solution to execute this PHP code in MT machine?
impossible. mikrotik router is not a webserver. having a php server on the router would mean much trouble.
Second that. Please don’t ever put PHP or something like that on it. That would be causing lots of trouble nobody really wants.
