preg_match array items in string?

Question

Lets say I have an array of bad words:

$badwords = array(\"one\", \"two\", \"three\");

And random string:

$string = \"some

Here is the bad word filter I use and it works great:

private static $bad_name = array("word1", "word2", "word3");

// This will check for exact words only. so "ass" will be found and flagged 
// but not "classic"

$badFound = preg_match("/\b(" . implode(self::$bad_name,"|") . ")\b/i", $name_in);

Then I have another variable with select strings to match:

// This will match "ass" as well as "classic" and flag it

private static $forbidden_name = array("word1", "word2", "word3");

$forbiddenFound = preg_match("/(" . implode(self::$forbidden_name,"|") . ")/i", $name_in);

Then I run an if on it:

if ($badFound) {
   return FALSE;
} elseif ($forbiddenFound) {
   return FALSE;
} else {
   return TRUE;
}

Hope this helps. Ask if you need me to clarify anything.
