Basic eBay Search Parsing

To use this script, simply call the PHP file and append "?searchstring=<text_you_want_to_search>" onto the URL. So, for instance -- "" would bring back results for "Batman". Again, this is a semi-basic way to parse eBay's pages to serve only as an example of a way to accomplish similar tasks. It will likely not work in the near future, as eBay is constantly changing it's pages.. however the basic premises of parsing should be applicable to other uses. Currently this script would only grab the first page of auction results (ie.. the auctions ending soonest) and you are limited to searching for single words. Further coding would have to be done to grab additional pages of results or entering multiple search terms. In addition, the results would also need to be cleaned up further to use this for anything practical, as they will contain dirty HTML code (extra tags).

The full source code to this script is below:

$file fopen("$URL""r");
$r "";

strlen($data) != 0);

$ebayTABLEArray preg_split ("/<table.*?>/"$r);

// now try to find which <table> contains the search results are
for($x=0$x<count($ebayTABLEArray); $x++){
strstr($ebayTABLEArray[$x],"Customize Display")){ // this is text
$resultTable $x+1;

$ebayTRArray preg_split("/<tr.*?>/",$ebayTABLEArray[$resultTable]);

"<BR><B>Ebay Results:</B><BR><BR>";
$end $start count($ebayTRArray);

$ebayTDArray preg_split ("/<td.*?>/",$ebayTRArray[$i]);
$item strip_tags($match[0],"<A></A>");
$item_name $item;
$price strip_tags($ebayTDArray[6]);
// see if there's a Buy-It-Now price
$priceArray explode("$",$price);
$item_price $priceArray[1];
$item_bin $priceArray[1];
$item_bids strip_tags($ebayTDArray[7]);
$item_timeleft strip_tags($ebayTDArray[8]);

$item_name." ".$item_price." ".$item_bids." ".$item_timeleft."<BR>";

Possibly out of date for the new ebay, we will see. However, this is the BEST explanation of preg_split I have ever seen and I can see it's potential for many things. Many thanks

I don't have specifics on how to pass the password credentials to a site, but I know it's possible because there are programs and applications out there that are capable of doing this.
Completed listings?

Is it possible to search through completed listings? So, is it possible to log-in (without the visitor of my site knowing the log-in/password) and extract these auctions as well?

Thanks for writing this article. I appreciate all the work you've put into it and wanted to say IT WORKS! :O)

Best article with a working example I have ever found online!
