pos = 0;}#定義指標置0 rewindpublic function rewind(){echo __METHOD__,"
";$this->pos=0;}#定義valid 方法public function valid(){#判斷是否可行echo __METHOD__,"
";if(isset($this->arr[$this->pos])){return isset($this->arr[$this->pos]);}}#擷取當前的值 currentpublic function current(){echo __METHOD__,"
";return $this->arr[$this->pos];}#擷取當前的索引值 keypublic function key(){echo __METHOD__,"
";return $this->pos;}#指標下移函數public function next(){echo __METHOD__,"
";++$this->pos;}}#執行個體化對象$test = new MyIterator();#遍曆對象foreach($test as $key=>$val){var_dump($key,$val);echo '';}
