Noob need's help with php :D

[darklight]

OK, I'm messing around with PHP.  I am trying to stop it from writing bad words to a file.  Can anyone help?

 

<?

$request = strip_tags($_POST['textfield3']);

$engine = $_POST['engine'];

//$image = $_POST['Image'];

 

 

  $IP = $_SERVER['REMOTE_ADDR'];

  $file=fopen("IPs/$IP".".htm","a+");

                  fwrite($file,"$IP Searched: $request<br><hr><br>");

                  fclose($file);

 

 

  if ($engine == 'Google') {

    if($request != 'porn' || $request != 'sex' || $request != 'fuck' || $request != 'shit') {

  $file=fopen("searches.txt","a+");

fwrite($file,' '."<a href=http://www.google.com/search?q=$request>$request - $engine</a>\n");

fclose($file);

  }

header("Location: http://www.google.com/search?q=$request");

}

 

/*

  if ($engine == 'Google' && $image == '0' ) {

  $file=fopen("searches.txt","a+");

fwrite($file,' '."<a href=http://images.google.com/images?hl=en&q=$request&btnG=Search+Images&gbv=2>$request - $engine (Images)</a>\n");

fclose($file);

header("Location: http://images.google.com/images?hl=en&q=$request&btnG=Search+Images&gbv=2");

}

set a words file with one pword per line and say foreach line (with fget i think) if the request equals that (preq_match or str_replace) then echo they searched soemthgin abd and die the script.
