redirect script

Anon

I have two php3 scripts.

index.php3 that has a bunch of html in it and links to pages.

redirect.php3 which just redirects the user to a page I specify.

I have a html link in index.php3

<a href="redirect.php3?action=goto&url=http://www.yahoo.com">yahoo.com</a>

and

<a href="redirect.php3?action=goto&url=http://www.excite.com">excite.com</a>

I want the redirect script to redirect the user to whatever the string says

anything after ...url="('domain.com')" will redirect the user to that page.

Can someone do this for me, i'm knew to php

<?PHP

header("Location: $url");

There must not be ANY html, not even a space, before this code.

Note that this does not test for the value of $action; that part is up to you.

Is there a way to dynamically perform redirection (in my case based on an IF statement) in the MIDDLE of an HTML document? (ie. after header and tags have been sent)

Anon

If you have PHP4 installed, you can turn on output buffering, which will let you use header() anywhere in the script.

It would be cleaner, though, to rewrite your code.

Anon

Header information must be posted first as well as cookie setting. If you don't you will get an error.

So is there a way to check if information has already been echo'd/printed to the browser to avoid such an error?

I suppose buffering would be a solution but to be extra protective something like

if( ! StuffAlreadySentToBrowser() ) {
Header("Location: http://www.php.net");
} // end if

would be really nice! Is there a
StuffAlreadySentToBrowser()
function in existence?
