Hi The Little Guy
To remove the file name and its extention, you have to write php script or use mod_rewrite module.
I want to show you mod_rewrite,apache module.To use this module you have a apache server,and there is a .htaccess file your host. You modify this file to change URLs.You can write and examine that rules ,
RewriteEngine On
RewriteBase /
RewriteRule ^school/images/(.*)$ images/$1
RewriteRule ^school/(.*).html index.php?id=$1
After this rule you can use www.xxx.com/school/1.html so you hide your .php extension if you want remove extensions complately,use that
RewriteEngine On
RewriteBase /
RewriteRule ^(.*) index.php?id=$1
then you can use www.xx.com/1 for example.
take care,bye
