Cannot modify header information - headers already sent

[TheLab]

Hello people

I was looking my error log on the server and i found this line:

[Tue Jan 13 05:49:57 2004] [error] PHP Warning:  Cannot modify header information - headers already sent by (output started at /home/***/***/announcement.php:1) in /home/***/***/admin/functions.php on line 1667

In the admin/functions.php on line 1667 i have this one:

setcookie($name, $value, $expire, $cookiepath, $cookiedomain, $secure);

The lines near it says:

  if (defined('USE_COOKIE_WORKAROUND')) {
    // It's been reported that there's a bug in PHP 4.2.0/4.2.1 with Apache 2 causing setcookie() to not work correctly.
    // This is the workaround. If you need to use this code, please add:
    //      define('USE_COOKIE_WORKAROUND', 1);
    // to your config.php.

    if (!$value) {
      // need to do this so IE deletes the cookie correctly
      $expire = time() - 31536001;
      $value = 'deleted';
    }
    $cookieheader = "Set-Cookie: $name=".urlencode($value);
    if ($expire) {
    	$cookieheader .= '; expires='.gmdate('D, d-M-Y H:i:s', $expire).' GMT';
    }
    if ($cookiepath) {
      $cookieheader .= "; path=$cookiepath";
    }
    if ($cookiedomain) {
      $cookieheader .= "; domain=$cookiedomain";
    }
    if ($secure) {
      $cookieheader .= '; secure';
    }
    header($cookieheader, false); // force multiple headers of same type
  } else {
    setcookie($name, $value, $expire, $cookiepath, $cookiedomain, $secure);
  }

}

Any ideas on that?! :ermm:

Now it should be ok, i changed my email and i forgot i had to put it on the vb customer site.

[TheLab]

Any ideas on the problem?

[TheLab]

Never mind.. i figured it out

[assassingod]

These errors are usually occured by whitespaces after the ?> in the file mentioned. Try removing an spaces ?> may have after it.

[Dean C]

Or before the <?php too

[TheLab]

Yeap, that was the error.. i search all my phps and i had a ton of empty spaces lol.

Thanx guys
