? Proper header() code ? 1

[NevadaJones]

If I have $url set to:

$url = "

http://redirecttohere.com/index.php";

Which is the proper way to write the header() line?

Header ("Location: " . $url);

Header("Location: $url");

 

[jpadie]

they are both fine.

this would not be fine

header('Location: $url');

as variables are not expanded within single quotes.

Thanks for the reply. The second header() example of my OP is what I have been and will continue to use now.

 

[jpadie]

there is some evidence to suggest that this form

header('Location:'.$url);

is materially faster.

this applies across all string functions.

 

[NevadaJones]

Then that is what I will start using.

Thanks
