Good morning.
I need that please put the commands to me so that a folder that by default does not allow to create nor to eliminate anything in its interior, allows it. I have Ubuntu Mate, and I am practicing with PHP in my localhost, but when I try to create a text document with the FOPEN function it says "permission denied". I came to the conclusion that the problem is not PHP but LINUX. And also please the commands to reset it for when I finish my practices. Is it unsafe to do this? Could someone enter my local host from the internet or not? Thanks.
