I don't get why this isn't creating a text file

Question

I'm suppose to create a short quiz and when you hit submit it takes you to a results page that shows the person's name, score, correct answers to the questions, time, and date and it also saves that data and keeps building the history of people who took the test. Here's what I have and I just don't know why it isn't working. I'm really new to PHP so I know I'm probably doing something stupid.

Answer 1

Looking at PHP's fopen function it should return false upon error, and produce a warning.

You can check the return value directly in the code:

$myfile = fopen("results.txt", "a");
if (!$myfile) {
  echo("file could not be created");
}

But to check the exact error message, you have to look at the webpage you created to check for a warning logs, or in your server's logs.

It is possible that the server does not allow files to be created by HTTP clients. Make sure to write the file to a safe directory, with the proper permissions.
