Remove Swear Words From Variable

[d_barszczak]

I am currently designing a Flash PHP MYSQL Chatroom which will allow users to have a chatroom on their website but hosted from mine.

The early beta version is availerble on my website for viewing.

I would like to add a content filter option to the client that stops users from submitting certain words so i need a way of removing or detecting certain words from a variable.

Once i do this i will be able to cycle through an array of words which are stored in a mysql database.

All this is done but just can't seem to find the command to find the words withing the variable.

[code]
foreach ($unallowed as $badword)
{
preg_replace ("/$badword/", "", $text);
}
[/code]
