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. -- David Robley Techno-JoaT, Web Maintainer, Mail List Admin, etc CENTRE FOR INJURY STUDIES Flinders University, SOUTH AUSTRALIA I failed attitude in school.
