Stupid me. I didn't remember that file() leaves the end of lines in the
strings, so adding them is unnecessary.
Change fputs($handler, "$line\n", 512);
to -> fputs($handler, "$line", 512);
Maybe now...
I should rtfm... It says right there: "Each element of the array corresponds
to a line in the file, *with the newline still attached*".
Because of this, each time you saved the file, it doubled the lines... Thus
one line and 15 empty lines...
