Dead Drift Crayfish pattern

This is another great crayfish pattern.

// Construct the full URL of your Product Ad Widget request
$strUrl = "http://www.avantlink.com/product_ad_widget/paw.php?pawid=2423&pw=4260&output=html&page=" . intval($_GET['paw_page']);

// Make the actual Product Ad Widget request
$strHtml = file_get_contents($strUrl);

// If your Product Ad Widget will contain more then one page of results you can include
// the following function call to add pagination to your display.
//
// The default is to show simple pagination links like: < Prev Next >
// If you change the boolean in the function call from true to false it will output full pagination links (eg. < Prev | 1 | 2 | 3 | Next >)
$strHtml = str_replace(““, getPawPagination($strHtml, true), $strHtml);

// Stream back the response
echo $strHtml;
