What is PHP's version of Response.Redirect? 1

[James1981]

Hi,

I'm new to PHP but am fluent in ASP. I want to redirect the browser to another URL in the same way that ASP uses Response.Redirect(url), but in PHP.

Is there an easy way?

Thanks in advance

James.

Like this:

<?php

header (&quot;Location: [URL unfurl="true"]http://www.mysite.com&quot;);[/URL]

?>

I have tried this but I get an error:

Warning: Cannot add header information - headers already sent by (path....)

anyway round this?

Yes.

Make sure that your script outputs no text to the browser before using header() for anything. ______________________________________________________________________

Know, too, that any warnings or errors that are printed to the browser screen count also count as output for the purpose of the header() function. ______________________________________________________________________

What happens if i need to output something to HTML using say echo "something" and this comes before the header() call?

How do i get round this?

Cheers
James.

You never need to output before header() Regards

how about this scenario?

echo "something";
if (condition)
header(location: "url"
echo "condition is false";

Move the if to before the echo line. //Daniel

Anything that affects the HTTP headers that PHP and the web server will send to the client must be done before any content is sent. This includes but is not limited to anything you do with header() [

http://www.php.net/manual/en/function.header.php

], setcookie() [

http://www.php.net/manual/en/function.setcookie.php

], session_start() [

http://www.php.net/manual/en/function.session-start.php

], and session_cache_limiter() [

http://www.php.net/manual/en/function.session-cache-limiter.php

]. This is because PHP sends data to the browser, whether headers or content, as it is being produced.

There is a way around this: output buffering [

http://www.php.net/manual/en/ref.outcontrol.php

]. With output buffering, you can produce output in any order you wish, then send it all at once. You take a performance hit using output buffering, however, as PHP has to cache the output until ordered to send it. ______________________________________________________________________
