Hi

I have a bad word filter lets say "hello" is a bad word

it will replace it by Violation, but if you put in HELLO it won't filter it.

How can I filter all types like HeLlO of hEllO

 

At the Moment i have

$bad_words = explode('|', 'hello');
foreach ($bad_words as $naughty){
$txt = str_replace("$naughty", "<font color=darkred><b><a href=tos.php>Violation</a></b></font>", $txt);
}

case-insensitive preg_replace:

 

$text = preg_replace("/foo/i", "blah", $text);

 

the i makes it case-insensitive

$filters = array('hello');
$replace = null;
$new_string = null;
$input = "heLlO";
foreach($filters as $filter){
    $input = preg_replace("/$filter/i", $replace, $input);
}
echo $input;
