What module should I install for php? I am trying to import a rule for facebook autopost in Configuration>Workflow>Rules, but after I click import button, I receive the error message below. I don't know which php module I have to install. I have searched on drupal site but I don't figure out which module I have to install.

Regards,
You should enable PHP Filter modules under CORE . Go to /admin/modules and find PHP Filter module and enable



It allows embedded PHP code to be evaluated
