How to pass multidimensional in URL with php

Question

I want to know the way of passing multidimensional in URL with php.
I have an array like this

$number  = $_SESSION["number"];  
$number = $number+1;  
$_SESSION["number"] = $number;  
$_SESSION['count']$number]=array($_POST['buy_app_page'],$_POST['x'],$_POST['y'],$_POST['w'],$_POST['h'],$_POST['selected_values'],$number);
$pixels_detail=$_SESSION['count'];
$pixels_detail=$_SESSION['count'];

I want to pass the session data stored in the $pixels_detail variable to url. I tried to to this but it show a blank parameter without any value in the url.

Actually am storing cart data in an session array and have two buttons when the user done adding products he/she clicks on the continue button this is where I want to the whole session data to be passed to the next page in any way, using url or someother I haven't any idea now!

Please Help.

Answer 1

Why do you want to pass data to the url? Usually storing it in the session is the best way to do it. If you want to pass complex data in the URL you might have a look at the serialize() and unserialize() funtions of PHP.

There is also the really nice funtion http_build_query() that converts complex data. But be aware of the 4096 character limit of a query string. I would really recommend to read the data from the session as far as you don't have any argument against it. You might pass only one parameter with the button and then read the corresponding data from the session.
