SpamBlocker

Spam Blocker is a CakePHP Behavior that automatically before after a comment is made. Each comment is tested upon a point system to determine if it should be approved, set to pending (high points), or marked as spam / deleted (low points).

/**

	if (mb_strlen($text) > $limit) {
		$text = strip_tags($text);
		$text = mb_substr($text, 0, $limit);
		$text = mb_substr($text, 0, -(mb_strlen(mb_strrchr($text, ' '))));
		$text = $text . $ending;
