######################################################
#
# Function to check text content for bad words and replace it
# very useful for Guestbook Scripts.
#
# simply edit the $word_list array and add the words you don`t want
# to read on your website. $contra is the string to replace bad word
#
# example text checking:
# $temp_text = check_content($content);
# if ($temp_text != FALSE) {
# $content = nl2br(addslashes($temp_text));
# } else {
# $content = nl2br(addslashes($content));
# }
#
# function written by Henning Jödden henning@wonderpixel.de
# no copyrights, use it as you like
#
# function is written in PHP3 so it can be used on most Webservers
# with PHP4 you can modify it with substr_replace() AND/OR stristr() to
# make it faster.
#
# send any comments to henning@wonderpixel.de thnx for using this snippet.
