Problem with guestbook badword filter

Hi,

I've created a small guestbook in PHP, now everything works fine except my
badword filter.
This is the code I use:
$dirty_words = file("dirty_words.txt");

for ($word_count = 0; $word_count < count($dirty_words); $word_count++){
$message = str_replace($dirty_words, "****", $guestbook[3]);
}

This doesn't do anything! Can somebody please help me?

Thanks,
Maarten

What are you doing with $message?

Should be:

$guestbook[3] = str_replace($dirty_words, "****", $guestbook[3]);

$message is just the name a give to the variable after the bad words have
been stripped.
I know that that isn't the problem...
But what is?

Help...

Do you have a script for this? Not sure what guestbook[3] is.

I thought you would need a file pointer to open the .txt file like a call to
fopen("dirty_words.txt").

Or is it possible to use the following:
..................

$badword=array("badword1","badword2","badword3");
foreach($badword as $word)
{
$message=str_replace()$badword,"*****",$message);
}
echo $message;
................
Please advise.

Many thanks for your assistance.

Hi,

The guestbook[3] is just the message part of my guestbook which I get from a
txt-file.
This is the code I now use and it works:
// Filter out the dirty words
$dirty_words = array('dirty', 'dirty');
foreach ($dirty_words as $word){
$guestbook[3] = eregi_replace($word, "", $guestbook[3]);
}
But now I want to be able to read the dirty words from an array in my script
but from a txt-file which is easier to update. But It doesn't seem to work!

I actually ran the script and found out why you were having problems. There
were some trailing characters that you need to trim in order for the match
to work. I added a trim() and it works fine.

$dirty_words = file("dirty_words.txt");

foreach ($dirty_words as $word){
$guestbook[3]= str_replace(trim($word), "****", $guestbook[3]);
}
