     }
    
      public function verify(){
         $type = isset($_GET['type'])?$_GET['type']:'gif';
                   import("@.ORG.Image");
                   Image::buildImageVerify(4,1,$type);

帮忙解决。。。小弟急求助。。还有我访问验证方法的时候显示的都是乱码

复制代码 public function verify(){     $type = isset($_GET['type'])?$_GET['type']:'gif';     header("content-type:image/$type");     import("@.ORG.Image");     Image::buildImageVerify(4,1,$type);   }

补充。Image中载入了String的ORG扩展。请适当修改
