Heh. File handling must be a bit different in Perl :-) Your code above
doesn't use the file descriptor (or file handle, if you prefer, or file
pointer) that is returned by the fopen function.
1 <?php
2 $file = "news.txt";
3 $fp = fopen ($file, "r");
4 $fs = filesize ($file);
5 while (!feof($fp))
6 {
7 $content = (fgets ($fp, $fs));
8 }
9 ?>
However, you might be as well off to use the file() function to read the
file into an array; you can then process the array with list/each and
write it out line by line.
