Convert eBay Link Generator results into bitly.com link

I managed a small PHP script that takes the eBay product searched and converts it into promote eBay link.

It goes like this:

1. user searches for example: ocz vertex
2. clicks on "Submit" and gets the results in following format

http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=10&pub=5575165347&toolid=10001&campid=5337851510&customid=&icep_uq=ocz vertex&icep_sellerId=&icep_ex_kw=&icep_sortBy=15&icep_catId=&icep_minPrice=&icep_maxPrice=&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg

(Can't fix that space in the link generated between ocz and vertex words)

Now, the result is nice, but I want to shorten it via bitly.com account using their API.
Basicly I want it to generate and convert the full eBay link results into small bitly.com link (http://ebay.to/2scU91k for example) and to see that link on my bitly account.

The process would go like this:

• User search for term like ocz vertex
• click on "Submit"
• get the ebay.to short link (while the real process is in background, converts to rover.ebay.com address and then to ebay.to using my bitly.com credentials)

I found that and that and especially that, but didn't understand how do I implement the results as a new bitly convert.

Here's the PHP code:
