1、dirname：获取前缀

        $oBasePath = dirname($oBasePath)."/fckeditor/";

2、addslashes：转义字符，把在文本里输入的单引号，一样的传入到数据库中

3、fckeditor的使用    

    <?php    

       include("fckeditor/fckeditor.php");    

       $oBasePath = $_SERVER[‘PHP_SELF‘];    

       $oBasePath = dirname($oBasePath)."/fckeditor/";

       $oFCKeditor = new FCKeditor(‘FCKeditor1‘);    

       $oFCKeditor->BasePath = $oBasePath ;    

       $oFCKeditor->Height = "500px";

     //    $oFCKeditor->ToolbarSet = "Basic";    

      $oFCKeditor->Create() ;    

  ?>
