Php 向会话数组中添加值

我正在创建一个购物车应用程序。我有将每个项目添加到会话数组中的逻辑，但我不知道如何将值添加到会话数组中。有人能帮我吗？

将每个项目添加到一个数组中，并将其分配给如下会话变量

session_start();
$_SESSION['cart'] = array( ... );

$_SESSION['cart'][0]
$_SESSION['cart'][1]
.
.
.

因此，您可以像这样访问每个项目

session_start();
$_SESSION['cart'] = array( ... );

$_SESSION['cart'][0]
$_SESSION['cart'][1]
.
.
.

向会话数组添加值非常简单

$_SESSION['variable1'] = "Test1"; 
$_SESSION['variable2'] = "Test2";

1.在脚本顶部添加以下行以启动会话

session_start();

2.使用以下示例向会话数组添加值

$_SESSION['variable1'] = "Test1"; 
$_SESSION['variable2'] = "Test2";

3.检索那些会话数组值，如下例所示

//Prints whole session array by using below line 
print_r($_SESSION); 
//print individual values by using below examples 
echo isset($_SESSION['variable1']) ? $_SESSION['variable1'] : '';
echo isset($_SESSION['variable2']) ? $_SESSION['variable2'] : '';
