RE: [PHP] Naughty Word Catcher

[Maxim Maletsky]

Alright ... the last review ('cause I never like what I write ... )

here:

function naughty_words($text) {
  $query="select naughty_words from prude_list";
  $result=mysql_query($query);
  while ($loop=mysql_fetch_array($result)) {
     if(stristr("$text","$loop[naughty_words]")) {
                return true;
     }
  }
}


if(!nasty_words($text))
   header("Location: error.php?reason=prudes_wont_like_it");
else
   header("Location: insert_stuff.php?comment=$text");


Cheers,
Maxim Maletsky

Actually your function does header() on each loop ... 

This is correct ..  

<snip>

  $query="select naughty_words from prude_list";
  $result=mysql_query($query);
  while ($loop=mysql_fetch_array($result)) {
     if(stristr("$block_of_text","$loop[naughty_words]")) {
                $Gotcha = 1;
          Break;
     }

  if(!$Gotcha)
     header("Location: error.php?reason=prudes_wont_like_it");
  else
     header("Location: insert_stuff.php?comment=$block_of_text");

</snip>

Cheers,

Hi all,

Ive just been asked whether I can do the following task.....

When a block of text is submitted via a web form, for it to be checked for 
offensive words, and rejected if there is.

So I put my brain hard to work and came up with a possibly solution. I know 
this method should work but im wondering if I should tackle it a different 
way.

This is just a rough, typed-off-the-top-of-my-head to show the method 
rather than correct code.

The idea was to have a list of offensive words or phrases in a MySQL 
database, and the script would take the block of text, and do the following

$query="select naughty_words from prude_list";
$result=mysql_query($query);
while ($loop=mysql_fetch_array($result)) {
     $naughty_word_checker =
stristr("$block_of_text","$loop[naughty_words]");
     if ($naughty_word_checker) {
         header("Location: error.php?reason=prudes_wont_like_it");
     } else {
         header("Location: insert_stuff.php?comment=$block_of_text");
     }
}


or is there a better, more efficient way of doing it. Im pretty sure the 
concept of above will work because if there is a match, stristr() should 
return text, otherwise it shouldnt return anything (or if im wrong, a 
little fine tuning will sort that out).


Thanks


Chris
