Presumably you've gotten it all working now. But I just wanted to mention something that I hope will aid you as you start into learning to program.

Always look at the error messages you're getting. Always start with the first one and figure out why you're getting it. After you've fixed it, move on to the next.

In the case of your code, first you'll get a syntax error on line seven, because there's no code block following the while(0) syntax.

The next syntax error will be your final for loop, which isn't terminated with a closing brace.

Your final foreach loop works as a statement modifier, so the comma between the "\n" and the foreach is unnecessary, and confusing.

If you get in the habit of looking at the error messages with an attitude of, "I should figure out what this is telling me, and why.", you'll find your emerging adventure in programming more fun.
