Problems with echoing $store->boxes->1->cost

[ryankentp]

Hello,

I am making a shopping cart that automatically decides what box to ship products ordered on my website in. The code connects to a mysql database and saves all the data, but I cannot find out how to echo the data, after it has been saved.

 

I know this is the problematic code:

<?php
echo $store->boxes->1->cost;
echo $store->boxes->2->cost;
?>

 

I believe it doesn't work because of the numbers (1 and 2). If you know what I can do to fix it without even needing to look at my code, please respond. If not, reading more may help you.

 

The source of the file is located at http://www.ryanpendleton.net/store.php

The output of the file is located at http://www.ryanpendleton.net/output.php

(I would have posted the code here, but I thought there was a little to much...)

 

After looking at the output, it could tell it was returning the right thing, but I can not find out how to echo the price or size of the boxes.

 

If you need me to clarify anything, don't hesitate to ask.

 

Thanks in Advance,

Ryan Pendleton

Why would you store stuff like that? Better if you don't answer that. Give this a try -

echo $store->boxes->quantity->1->cost;

Nope. That didn't work:

Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `'{'' or `'$''

 

The box information isn't inside quantity.

 

EDIT: Sorry, I mean isn't inside

The solution was the put the number in curly braces like below:

<?php
echo $store->boxes->{1}->cost;
echo $store->boxes->{2}->cost;
?>

It's because identifiers aren't allowed to start with digits. They must match the pattern ^[a-zA-Z_][a-zA-Z0-9_]*$ if you know regex. Otherwise you must use weird syntax to access them.
