好多事务，唉！
数组的操作

<?php
$arr=array('name'=>'test','price'=>'33','count'=>'333');

//print_r($arr);

  $_SESSION['products']=array(
              array('name'=>'echo','price'=>'2','count'=>'3'),
              array('name'=>'name','price'=>'100','count'=>'1'),
              array('name'=>'else','price'=>'200','count'=>'2'),
              );

   //向数组的开头写入值，测试成功
    array_push($_SESSION['products'],$arr);





    $_SESSION['products'][0]['name']='edit echo';
     unset($_SESSION['products'][0]);
    print_r($_SESSION['products']);

     //echo $_SESSION['products'][0]['name'];
  ?>

關於二維數組的刪除修改或是對比，我是通過foreach然後找到相同的key的值去修改裡面的值

    foreach ($_SESSION['products'] as $kkk)
          {
            if ($kkk['proid']==$_POST['oid'] && $kkk['produts']=="裝備")
            {
              $kkey=array_search($kkk,$_SESSION['products']);
              $_SESSION['products'][$kkey]['count']++;
              die("這個商品已經添加到購物車這個".$kkey);
            }
          }
