using header() after output was sent?

Copy linkTweet thisAlerts:

Hi, is there a way I can user the header() command after I printed something? What I am trying to do is something like:

[CODE]print(“you will be redirected after 3 seconds..”)
flush();sleep(3);
header(“location:page.php”);[/CODE]

but as you can imagine, I get the all known “headers already sent…”.
I know there are alternatives using javascript or meta but I would like to know if it’s possible to do in php

thanks in advance

@NogDogJun 29.2008 — You could send a "Refresh:" header instead of a "Location:" header. It would still have to be executed before any output is sent, though.
[code=php]
header("Refresh: 3;http://www.yoursite.com/page.php");
echo "<html><head><title>Redirecting...</title></head><body>n";
echo "<p>You will be redirected in a few seconds....</p></body></html>";
exit;
[/code]

/**
* redirect to a specific URL
* @param $url
*/

function redirect($url)
{
if (!headers_sent())
{

//If headers not sent yet... then do php redirect
header('Location: '.$url); exit;
}
else
{

//If headers are sent... do javascript redirect...
//if javascript disabled, do html redirect.
echo '<script type="text/javascript">';
echo 'window.location.href="'.$url.'";';
echo '</script>';
echo '<noscript>';
echo '<meta http-equiv="refresh" content="0;url='.$url.'" />';
echo '</noscript>'; exit;
}
}
[/code]

Success!
