You can pick any of many, but I'm more familiar with Prototype:

## credits.php
?php
/* ... */ // determine value for $credits
print min($credits, 0);

[PHP] Any Running Simple Ajax Sample for Php
Hi Heysem, So what you want is an ajax script that will call a php page every minute, and check for a result (assuming boolean) of 1 or 0? That shouldn't be too hard. First, I need to know more information about the page, such as the id tag of the element you want updated, and how severe the change. If it's a simple word, it's easy to do. If you could post more information (and possible what you have tried already, and maybe we can just fix that), I should be able to help you out more.
