[ciapug] Moderating message forums

[Tony Bibbs]

Here's the snippet I was referring to.  The first three variables define 
settings for the function:

$_CONF['censormode']    = 1;
$_CONF['censorreplace'] = '*censored*';
$_CONF['censorlist']    = array('firstbadword','secondbadword','etc');

function COM_checkWords( $Message )
{
     global $_CONF;

     $EditedMessage = $Message;

     if( $_CONF['censormode'] != 0 )
     {
         if( is_array( $_CONF['censorlist'] ))
         {
             $Replacement = $_CONF['censorreplace'];

             switch( $_CONF['censormode'])
             {
                 case 1: # Exact match
                     $RegExPrefix = '(\s*)';
                     $RegExSuffix = '(\W*)';
                     break;

                 case 2: # Word beginning
                     $RegExPrefix = '(\s*)';
                     $RegExSuffix = '(\w*)';
                     break;

                 case 3: # Word fragment
                     $RegExPrefix   = '(\w*)';
                     $RegExSuffix   = '(\w*)';
                     break;
             }

             for( $i = 0; $i < count( $_CONF['censorlist']); $i++ )
             {
                 $EditedMessage = eregi_replace( $RegExPrefix . 
$_CONF['censorlist'][$i] . $RegExSuffix, "\\1$Replacement\\2", 
$EditedMessage );
             }
         }
     }

     return $EditedMessage;
}
