Popshops SEO - PHP or Javascript for best Ranking

Hi Please look at these 2 pages below. They both display the same [login to view URL] Popshops 1. [login to view URL] contains the following php code snippet:- <?php # Determine the current base URL if(!isset($_SERVER['REQUEST_URI'])) { $psps_base_url = $_SERVER['PHP_SELF']; if (isset($HTTP_SERVER_VARS['QUERY_STRING'])) { $psps_base_url .= $HTTP_SERVER_VARS['QUERY_STRING']; } } else { $psps_base_url = $_SERVER['REQUEST_URI']; } $psps_parameters = ''; foreach ($_REQUEST as $key => $value) { if (strpos($key,"psps_") > -1 ) { $psps_parameters .= '&'.$key.'='.urlencode($value); $psps_base_url = str_replace('&'.$key.'='.urlencode($value), "", $psps_base_url); $psps_base_url = str_replace($key.'='.urlencode($value), "", $psps_base_url); } } $psps_parameters .= "&psps_show_search=true"; $psps_parameters .= "&psps_show_navigation=true"; $psps_parameters .= "&psps_show_products=true"; $psps_url = "?psps_base_url=".urlencode($psps_base_url); $psps_url="[login to view URL]$psps_url$psps_parameters"; # Include the shop if (function_exists('curl_init')) { $shop=curl_init(); curl_setopt($shop,CURLOPT_URL,$psps_url); curl_exec($shop); curl_close($shop); } else { readfile($psps_url); } ?> 2. [login to view URL] contains the following javascript code snippet:- <!-- PopShops store code starts here --> <script type="text/javascript" src="[login to view URL]"></script> <!-- PopShops store code ends here --> What I would like to know is:- 1. Which is the best code snippet to use for web browsers, robots, crawlers - php or javascript? 2. Which code snippet will get the best ranking and indexing? 3. Please explain why the code snippet you recommend is best? 4. What do web browsers, robots, crawlers actually see when the site is crawled indexed? 5. Any other comments about SEO for these Popshops pages using PHP or Javascript? I will select a few bidders so I get more than 1 view Many thanks
