 //one   
     $arr = array(array('name'=>'张三','age'=>'23','sex'=>'男'),array('name'=>'李四','age'=>'43','sex'=>'女'),array('name'=>'王五','age'=>'32','sex'=>'男'), array('name'=>'赵六','age'=>'12','sex'=>'女'));

     foreach($arr as $k=>$val)
     {
      echo $val['name'].$val['age'].$val['sex'] ."<br>";
     }
      echo "<p>"; 
//two
     $arr = array(array('张三','23','男'),array('李四','43','女'),array('王五','32','男'),array('赵六','12','女'));
     
     foreach($arr as $key=>$value)
     {
     foreach($value as $key2=>$value2)
     {
     echo $value2;
     }
     echo "<br>";
     }

     foreach($arr as $key=>$value)
