idea to create custom PHP block

i had this idea to create a block to write PHP, it would act like the custom HTML block, just for PHP. the block edit would have a textbox to edit, it will then save it to the $content variable passed to the PHP render function, and execute it.

it should be checked before execution for errors and injections and what not, but i think it can be realy useful.

will update later on.
hopefully 🙂
