Hello Arkin, how are you?
Can you post again the file swearword-censor.phps to download?

It doesn’t work at all for me :\

Graham:

$sql = “SELECT word FROM censor_words”;
//Or whatever your table/field is called
$result = mysql_query($sql);

if ($result || mysql_num_rows()>0)
while (list($word) = mysql_fetch_row())
$censor_words[] = $word;

This would put all of the words in censor words.

This may be due to your PHP settings tlehman, can you provide me more specific examples?

Nice Work. When I implement this code its only catching the first swear word in the sentence. If someone happens to have a sailor’s mouth, its not going to help. Any ideas?

I tried the filter. Its not that great because you can cheat it by simply playing around with the capitalization.

I have been working on a comprehensive swear filter for quite some time, this is a great start to eliminating some words based off a list but there are so many more ways to cheat the filter using special characters.

I have made a filter that scrubs the string several times and compares based on filters and punctuation, it is working quite well now, almost impossible to get anything through and the word list is only about 20 words long.

To make it run from a mysql DB, change the code in the 1st if statement to something like…

$sql = “SELECT words FROM censor_table”; //Or whatever your table/field is called
$result = mysql_query($sql);
$censor_words = mysql_fetch_array($result);

Not tested.

@6: I emailed you this reponse also:

It is possible to convert this to run from a mysql database/table instead of a text file by simply loading the mysql table into the swear words array instead of the text file.
