[PHP] Question on explode and join.

[Beauford]

Hi,

I have a form which I want to check for inappropriate words before it is
posted. I have used explode to put the string into an array using a space as
the delimiter and then I check it against another array that contains the
inappropriate words.
I then replace the inappropriate words with *'s and join the array back into
a string.

This works perfectly except for one thing.

If the word in the string has a any kind of punctuation after it (period,
comma) it won't be matched.

So if  moron is an inappropriate word then "you are a moron" works, but "you
are a moron." won't.

Any ideas?

Thanks

This is my code.

function badwords($string) {

        $language = array(contains the inappropriate words);

        $words = explode(" ",$string); 
        $count = count(explode(" ", $string)); 
        
        for($i = 0; $i < $count; $i++) {
                if(in_array(strtolower($words[$i]), $language)) {
                        $words[$i] = "*****";
                }
        }

        $newcomments = join(" ",$words);
        
        return $newcomments;
}
