difference between alternative syntax of header() with exit

Question

I m curious to know that is there any diffrence between

header('Location:index.php'); // using  capital  `L`
exit(); // using parenthesis

AND

header('location:index.php');
exit;

which one we should recommend to use?

According to the actual RFC for HTTP, you should use an uppercase "L", and an absolute URI:

header('Location: http://www.mysite.com/index.php');

As far as exit vs exit(), there is no difference. It is a language construct, not a function, and the parenthesis are optional. You may even use exit 0 or exit(0).

Section 4.2 says that field names are case-insensitive. However, it's conventional to use initial capitals.

Whitespace after the colon is also preferred, but not required. Again, read section 4.2.

There is no difference between exit; and exit();

and the Location should be written with a capital L
