feof() is a function that checks if a file has reached the end or not. (eof
= end of file)
while (!feof ($fp)) in whole means something like this
As long as the filepointer ($fp) is not at the end, do whatever that's
between { and } over and over again...
> Why are there 2 ) at the end?
Just because :-)
The first ) belongs to feof and the second ) belongs to while.

$buffer is just a variable that stores the result of fgets(). It could be
any name really...

You modify this line
echo $arr[4];
to this
echo $arr[4] . "\n"; // The . is a string concatenation operator. It simply
joins the two strings.
Now this would give you the same result in your browser, but if you view the
source in the browser you will see that the lines are separated. To do a
line break in the browser you have to insert the correct html (<br>)
instead.

www.php.net/manual/en/ is a very good start.
