Email format validation in Php using regular expressions

never ever include filename which you are including in htaccess url

example: RewriteRule ^admin/profile /admin.php?file=profile [NC]

in this first name after “domainname or ^ ” and filename you are using for reference is same

“ ^admin/” = “/admin.php?file=profile”

so give another name for filename reference.

like this RewriteRule ^admin/profile /master.php?file=profile [NC]

it worked.
