Updated PHP code to automatically bid/buy an eBay auction item

This code is now obsolete and has been updated again.

Updated code to automatically bid on an eBay item, I’m currently using it myself if a loop of searched items.

Most of the changes are improved return status checking. For testing use one cent items with free shipping.

// MAIN BIDDING FUNCTION
// this function performs no checking on the input variables
// $username  -  the eBay user name
// $password  -  the eBay user password
// $item      -  the eBay item number to bid on
// $bid       -  the bid amount in local currency i.e. 5.67
// $link      -  referral link, can leave empty i.e. '' or use 'http://ebay.com'
function place_bid($username, $password, $item, $bid, $link) {

	$cookies = dirname(__FILE__).'/cookies.txt';
	
	//set success as default false
	$success = false;
	$bid_success = false;
