Well we have some projects in our uni about creating HTML/CSS/JavaScript/PHP webpages, basic stuff, we then compress and email the files to them.
Now they want us to create the websites with Notepad++ and they specifically state "other frameworks are NOT allowed"... but I want to use JetBrains PhpStorm for obvious reasons!
The question is: is there anyway they can tell if I have used PhpStorm? Is there any signature on the code/file extension or something? If yes, how can I hide it?
No, I don't think so.
This is probably an exercise to teach you to look for errors yourself etc., rather than relying on automated tools.
If it is basic stuff, Notepad++ should be more than sufficient, though.
