hveing problems with costs adding up

[fazz]

I have a shopping cart, and each client that logs on has a budget spend -  am testing it with a budget of 5000.

 

So I have created this that works until the toal goes past 999

 

 

<?php
		  $Budget = $HTTP_GET_VARS['Budget'];
		  $TotalCart = $HTTP_SESSION_VARS["icNamco"]->col("Total");
		  echo number_format ($Budget - $TotalCart);
		  ?>

 

It deducts and gives me the correct total until it goes over 999 and the reverts to displaying 4,999

 

 

Can any one shine any light on this!

 

Merry christmas to everyone!

What does the function number_format contain?

 

And if you want your code to last more than a year or two, you should replace $HTTP_GET_VARS with $_GET, $HTTP_SESSION_VARS with $_SESSION

What does the function number_format contain?

 

It's a library function: http://php.net/number_format

Being a php newbie how do I apply this?

[fazz]

the number_format contains:

 

....."]->col("Total"); is the total from the shopping cart

 

$Budget is a total from the database related to the customer who has logged on it is just a text field with 5000.00 entered in to it

I have now found this and changed my code

<?php
				//Add up toal items and - from Budget cost: does not work correctley over 999.00
              $Budget = $HTTP_GET_VARS['Budget'];
		  $TotalCart = $HTTP_SESSION_VARS["icNamco"]->col("Total");
              $BudgetRemain = $Budget - $TotalCart;
		  echo number_format ($BudgetRemain, 0, "", ",");
		  ?>

 

I now have a budget of 485 when I add a total of 595 into my cart it says the remaining budet is '-110'

 

I add a second item of 415 and then the toal says £484 instead of - 594 I just can't seem to work it out?
