I was trying to add a text file through an iframe in order for my lecture to be able to see and mark my php code. The problem is that 000web.com where I hosted my site does not allow txt files for security reasons.
As a work around I tried to place my php code inside a textarea tag and this still does not work. I would highly appreciate it if someone can assist me with this issue. Basically I want to display my php code inside a php page so that it can be viewed by a visitor.
