By using the below code we redirect the page

echo '<script type="text/javascript">';
echo 'window.location.href="'.$page.'";';
echo '</script>';

Answer 2

echo "<script>window.location.href='yourPage.php'</script>";

Answer 3

You cannot set headers after outputting some text, so either you move the header call before the echo statements (fine in your case) or you use output buffering.

Answer 4

I use this function for redirect...

Which works in all situations..even if headers are already sent..or even javascript is disabled..

function redirect($url)
{
    if (!headers_sent())
    {    
        header('Location: '.$url);
        exit;
        }
    else
        {  
        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;
    }
}

Answer 5

You probably have already sent content to the browser before the php header is sent. This can be just a \n after a closing php tag ( ?> )

To find the place where unwanted output is generated canbe hard on bigger projects or long lines of classes extending each other. To find the problem you can do this:

 error_reporting(E_ALL); 
 ini_set("display_errors", 1);
 header("Location: https://mydomain.com/myLoginAdress/");
 die();

Strict error reporting will throw line and file of the output.

Answer 6

Redirecting via headers is illegal if any content has come through. Take out all the echos and it should work. If you do want there to be a message shown to the user before the redirect, you'll likely have to do it with JavaScript via location.href.
