database with php code

Hello in my database i have records that contain php code. i want to put these content on a php file. Here´s the problem: Suppose the content returned from the Db is: $codeFromDB = "<?do some processing?>"; if i do: echo $codeFromDB; i´d be writing the content to the returned html file, bu i´d like the content to be processed by php. I suppose "echo" is not the way to do it.. So.... what can i do?? thanks for your time Sérgio Mergen Web developer VIAVALE Internet
