The only thing that I didn't use here is the change in .htaccess file, so I type the url like this:
http://localhost/test_001/xcart_412/customer/SEO_listing.php
Base on what you said it should work this way, but I get this ERROR:
Parse error: parse error, unexpected T_VARIABLE in /Applications/MAMP/htdocs/test_001/xcart_412/customer/SEO_listing.php on line 12
