php echo单链元素多维数组

Question

I am passing arrays from a product page and using the $_GET['id'] to store product ids in 'id' then storing it in session['items'].

On the cart page, I would like to echo out only the 'id' elements of the array and not the qty. But I still want to keep the current code where $item and $value are echo.

Add-to-cart.php

**code
session_start();

$_SESSION['items'][]=array(     
                            'id'=>"'".$_GET['id']."'",
                            'qty'=> 1                           
                        );  
?>

Cart.php

**code
<?php
session_start();
foreach($_SESSION['items'] as $items=>$values)
{
foreach($values as $item=>$value)
{
//// I want to keep this, 
    echo $item;

    echo $value."<br/>";
    echo "</br>";
//// I want to keep this  
//// echo 'id' values here!
 }
}
?>

Answer 1

You'll want echo $value['id'];

<?php
session_start();
foreach($_SESSION['items'] as $items=>$values)
{
foreach($values as $item=>$value)
{
//// I want to keep this, 
    echo $item;

    echo $value."<br/>";
    echo "</br>";
    //// I want to keep this  
    echo $value['id'];
 }
}
?>
