Question

I have programmed this function

function bad_words($val){
    global $pre; 
    $sql = mysql_query("SELECT * FROM " . $pre . "BAD_WORDS") or die(mysql_error());
    $rs = mysql_fetch_assoc($sql); 
    if (mysql_num_rows($sql) > 0) { 
        $bad_words = $rs['BAD_WORD']; 
        $replace = $rs['REPLACE']; 
    } 
    $val = str_ireplace($bad_words, $replace, $val);
    return $val; 
}

BAD_WORDS Table (ID, BAD_WORD, REPLACE)

When I use this function it replaces word with id = 1 but doesn’t replace the other words.

What am I missing?

You are fetching only the first row from the table. You have to use a loop to iterate through
all the rows in the result set.

function bad_words($val)
{
global $pre;
$sql = mysql_query("SELECT * FROM " . $pre . "BAD_WORDS") or die(mysql_error());

if (mysql_num_rows($sql) > 0) {
   while($rs = mysql_fetch_assoc($sql)) {
      $bad_words[] = $rs['BAD_WORD'];
      $replace[] = $rs['REPLACE'];
   }
}
$val = str_ireplace($bad_words, $replace, $val);
return $val;
}
