i got no errors

[writng to a text file under linux]

first of all... i am newbie...

well i'm trying to code a simple guestbook. i have ubuntu 6.06. the problem is that i just can't write into a file. i guess it has something to do with permissions. but my file book.txt has em -rw -rw -rw.

here is my code:

[code]<?php
$path = "book.txt";
if ($action=='save'):
@$file = fopen($path, "r");
@$content = fread($file, filesize($path));
@FClose($file);
if (($message=="") or ($nick=="")):
echo "<p>Nie su vyplnene pozadovane udaje!</p>";
else:
$file = fopen($path, "w");
$str = "<div><h4>".$nick.", ".Date("d-m-Y, H:i:s")."</h4><p>".$message."</p></div>";
fputs($file, "$str");
fputs ($file, "$content");
FClose($file);

@$file = fopen($path, "r");
@fpassThru($file);
endif;
else:
@$file = fopen($path, "r");
@fpassThru($file);
endif;
?>[/code]

anyone has any ideas what to do... or is it the code's fault?
