save to file

I am trying to save to a text file. And I have managed to do that part now, but what happens is when I save to the file, all the lines get put into one big line in the file. I am creating a roster input that I adding to our website: No, name grade ..... The roster will contain 15 players So right now the implode puts everything on one line in the text file!!! So I am no sure if anybody can shed some light on this one. Thanks again Ryan <? //create a new file $fp = fopen("/place/on/server/" . $HTTP_POST_VARS['team'] , "w"); $file_data = implode("\t\", $_POST); //this would return values spit by tabs //write to the open file handle fwrite($fp, $file_data . "\r\n"); //close the file fclose($fp); ?>
