bad words filter integration
<p>I am trying to integrate php bad words filter 
The input is taken through $_REQUEST['qtitle'] and $_REQUEST['question']
But I am failed to do so </p>

<pre><code>$USERID = intval($_SESSION['USERID']);

if ($USERID &gt; 0)
{
$sess_ver = intval($_SESSION[VERIFIED]);
$verify_asker = intval($config['verify_asker']);
if($verify_asker == "1" &amp;&amp; $sess_ver == "0")
{
    $error = $lang['225'];
    $theme = "error.tpl";
}
else
{
    $theme = "ask.tpl";
    STemplate::assign('qtitle',htmlentities(strip_tags($_REQUEST['qtitle']), ENT_COMPAT, "UTF-8"));
    STemplate::assign('question',htmlentities(strip_tags($_REQUEST['question']), ENT_COMPAT, "UTF-8"));
    if($_REQUEST['subform'] != "")
    {
        $qtitle = htmlentities(strip_tags($_REQUEST['qtitle']), ENT_COMPAT, "UTF-8");
        $question = htmlentities(strip_tags($_REQUEST['question']), ENT_COMPAT, "UTF-8");
        $category = intval($_REQUEST['category']);


        if($qtitle == "")
        {
            $error = $lang['3'];
        }
        elseif($category &lt;= "0")
        {
            $error = $lang['4'];
        }
        else
        {
            if($config['approve_stories'] == "1")
            {
                $addtosql = ", active='0'";
            }
            $query="INSERT INTO posts SET USERID='".mysql_real_escape_string($USERID)."', title='".mysql_real_escape_string($qtitle)."',question='".mysql_real_escape_string($question)."', tags='".mysql_real_escape_string($qtitle)."', category='".mysql_real_escape_string($category)."', time_added='".time()."', date_added='".date("Y-m-d")."' $addtosql";
            $result=$conn-&gt;execute($query);
            $userid = mysql_insert_id();
            $message = $lang['5'];
        }
    }
}
}   

else
{
$question = htmlentities(strip_tags($_REQUEST['qtitle']), ENT_COMPAT, "UTF-8");
$redirect = base64_encode($thebaseurl."/ask?qtitle=".$question);
header("Location:$config[baseurl]/login?redirect=$redirect");exit;
}

<p>I am trying the following code but this code replaces every word (which is not included in the array)</p>

<pre><code>FUNCTION BadWordFilter(&amp;$text, $replace){

$bads = ARRAY (
  ARRAY("butt","b***"),
  ARRAY("poop","p***"),
  ARRAY("crap","c***")
);

  IF($replace==1) {                                        //we are replacing
  $remember = $text;

  FOR($i=0;$i&lt;sizeof($bads);$i++) {               //go through each bad word
       $text = EREGI_REPLACE($bads[$i][0],$bads[$i][1],$text); //replace it
  }

  IF($remember!=$text) RETURN 1;                     //if there are any changes, return 1

 } ELSE {                                                  //we are just checking

  FOR($i=0;$i&lt;sizeof($bads);$i++) {               //go through each bad word
       IF(EREGI($bads[$i][0],$text)) RETURN 1; //if we find any, return 1
  }     
 }
}
$qtitle = BadWordFilter($wordsToFilter,0); 
$qtitle = BadWordFilter($wordsToFilter,1); 
</code></pre>

<p>What I am missing here?</p>
