This task is very similar to what was previously done on a similar page (detail_page.php) in this website. For example if you go to the webpage: www.****.ca and click on any listed photo, the detail data will be shown in a webpage with a SEO friendly URL such as: http://www.****.ca/Ottawa-homes-for-sale/319-Summer-Sky-St This task was performed using .htaccess file (attached) and our existing sitemap (www.*****.ca/sitemap.php).
