<"/\[\[##(.*", array($this, 'getval'), $content); 
    } 
    return $content; 
  } 
 
  /** 白名单 key还原为value 
  * @param Array $matches 匹配white_list的key 
  * @return String white_list val 
  */ 
  private function getval($matches){ 
    return isset($this->_white_list[$matches[1]])"htmlcode">

<"content-type:text/html;charset=utf8"); 
 
  require("StrFilter.class.php"); 
 
  $white = array('屌丝', '曹操'); 
  $black = array('屌', '操'); 
 
  $content = "我操,曹操你是屌丝,我屌你啊"; 
 
  $obj = new StrFilter($white, $black);
