Redirect with header doesn't work

Question

Possible Duplicate:
Headers already sent by PHP

i don't know why if i call this file in standalone it works but if i call it inside my site it doesnt... but if i use the

echo "<br /><a href='".$url."'>Login with your Twitter account</a>"

in place of

header("Location: ".$url."");

it works... i would like to automatize the process instead of asking everytime to connect with twitter.

the code:

<?php
session_start();
require_once('twitteroauth/twitteroauth.php');
require_once('config.php');
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
$request_token = $connection->getRequestToken(OAUTH_CALLBACK);
$_SESSION['oauth_token'] = $token = $request_token['oauth_token'];
$_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret'];
switch ($connection->http_code) {
case 200:
$url = $connection->getAuthorizeURL($token);
//echo "<br /><a href='".$url."'>Login with your Twitter account</a>";
header("Location: ".$url."");
break;
default:
echo 'Could not connect to Twitter. Refresh the page or try again later.';
}
?>

if you have an echo or any html before the redirect it wont work unless you have buffering enabled — ianace, Jan 09 '13 at 13:09
usually problems with headers and echos can be solved with an call of ob_start() at the start of your code — x4rf41, Jan 09 '13 at 13:10
i have error reporting enable and nothing happens it goes in loop — Cavi Andrea Cavicchini, Jan 09 '13 at 13:16
"it goes in loop" does that mean your script doesnt finish executing? does the php script reach the line with header() ? have you tried ob_start() directly after — x4rf41, Jan 09 '13 at 13:23
i tried ob_start(), nothing happens. the $url link to the oauth tool of twitter, if i try the php file in standalone it works fine — Cavi Andrea Cavicchini, Jan 09 '13 at 13:55
[SOLVED] the problem wasn't the php, it was the javascript that call the php — Cavi Andrea Cavicchini, Jan 09 '13 at 15:39

Make sure to remove any white spaces before the <?php opening tag.
