1. Try writing FizzBuzz in PHP

Remember the rules:

Write a script that, for the numbers 1 to 100, prints "Fizz" if the number is divisible by 3, "Buzz" if by 5, "FizzBuzz" if by both, and the number if none of the above.

Hint: It's literally exactly the same as in Javascript, except variable names have to begin with $ and you don't use var, and you write echo instead of console.log.

2. Make the output go into a file

Try copying, pasting, and running this line in your script:

file_put_contents("hello.txt", "Hello, world!", FILE_APPEND);

• Run it multiple times. What happens?
• Run it without FILE_APPEND. What's different?
• Try changing hello.txt to another string. What happens?

Now, change this line so that it writes the output of your FizzBuzz program -- "1 2 Fizz 4 Buzz..." and so forth -- to a file. The file can be named anything.

3. Instead of always using 100, GET the number

That is: if the user goes to a URL like localhost/script.php?mynumber=29, FizzBuzz will run for the numbers 1 - 29.

Hint: GET parameters come from the URL. If your URL is localhost/foo.php?myname=john, it creates a GET parameter called myname with the value of john.

Hint 2: All the GET parameters are in an array called $_GET. You retrieve values from an array just like you would in Javascript.
