header ("Location... order

[Anon]

Hi

If I do a redirection in PHP will the browser redirect before the code has finished executing. I mean will it be faster to the user if I put the header("location:... line at the top of the script before I do all sort of slow db access etc rather than put this at the end of the script. BTW the application is a banner ad system - i have been trying a system where the next banner is fond and cached for speedy access the next time the script runs so i can do the above.

Hope I'm not being too confusing.

Thanks

Will

When using header('Location: <URL>') the "header" acts like "exit". It terminates the script nicely!

That means that any code after the header('Location: ') is NOT executed. That's just the way it is. Just remember that "header" can be used for other things than redirecting! =8-)

Are you 100% sure on this as I have been sucessfully using a script that has alot code after the header("Location: <URL>") line and it seems to be working fine?

psuedocode:

LOOK UP NEXT BANNER IN 'NEXTAD' TABLE

HEADER("Location: <BANNER URL>")

LOG BANNER IN LOG TABLE
INCREMENT BANNER SHOWS IN MEMBER TABLE
WORKOUT NEXT AD FOR THIS MEMBER AND ENTER IN 'NEXTAD' TABLE.

The whole reason I have done this 'NEXTAD' table idea is so I can have most of the code after the header redirect - I thought this may be faster. But it does seem to work okay at least?

Thanks
