fputs/fgets working irregularly

Hi all, I'm having some trouble getting my basic news script to work. Here is the code: $fp = fopen("data/prev.txt","r"); while (!feof ($fp)) { $pr = fgets($fp, 4096); } fclose($fp); $fp = fopen("data/news.txt","r"); while (!feof ($fp)) { $ag = fgets($fp, 4096); } fclose($fp); $fp = fopen("data/news.txt","w"); $np = fputs($fp,$pr); fclose($fp); $fp = fopen("data/news.txt","a"); $ng = fputs($fp,$ag); fclose($fp); The news.txt does not append what is stored in $pr for some reason. I can't put my finger on what the problem is, the file is chmod correctly as well. Can anyone help? Thanks, Kris
