I know this sounds like a stupid question, but I can't get my head around this problem. Basically I want to quit the script only if the folder in the directory already exists but all I get is the blank page with the echo "la cartella esiste" I guess this is because of the exit function. What I want is to have the message displayed on the page itself just like the other errors displayed, but without carrying on with the code. Do you have any suggestion on how to proceed?
