Found some sample code + documentation here. I integrate netsuite with some kohana based site. I've thrown up two snippets that I use for easing development, a getNetsuiteConnection() method and a snippet used for getting a list of custom fields in a given record.
Update:
Found some more resources recently (mostly targeted at using NetSuite via the PHP framework).
- NetSuite Global Scope Problem
- Getting a List of Customers
- NetSuite Tips & Tricks
- Tips & Code Samples
08/12 Update: If you are working with ruby, checkout this gem which implements a portion of the NetSuite SOAP API.
