Try to change your function in this way:


function filter($string)
{
  $pattern[0] = 'fuck';
  $pattern[1] = 'ass';
  $pattern[2] = 'shit';
  $replacement = 'beep';
  
  $pattern=implode('|',$pattern);
  #matches only whole words 
  return preg_replace("/\b($pattern)\b/i", $replacement, $string);
}

Well as long as your function works, my solution will work. Perhaps use this instead:

 

<?php

function filter($string, $replace) {
$banned = array("fuck", "ass", "shit");
foreach($banned as $word) {
  $string = str_replace($word, $replace, $string);
}
return $string;
}

$host= 'localhost'; 
$username= 'root'; 
$password= ''; 
$db_name= 'guest'; 
$tbl_name= 'book';

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect server"); 
mysql_select_db("$db_name")or die("cannot select DB");

$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);

while($rows = mysql_fetch_array($result)){

foreach($rows as $key => $value) {
$rows[$key] = filter($value, "beep");
}

?>
