PHP标头和刷新无法正常工作

My server running in PHP 5.2.9, When I using refresh and header functions it's not working. Here is my code

header("location: index.php");

header( "Refresh: 0;" );

Previously I'm working in a different server, It's working correctly. How can I solve this problem?

this is my complete code

if($_POST['sign_in'])
{
    $email = $_POST['email'];
    $password = $_POST['password'];
    $sql = "SELECT * FROM tbl_members WHERE m_email='$email' and m_password='$password'";
    $res = mysql_query($sql);
    $count = mysql_num_rows($res);
    if($count==1)
    {
        session_register("email");
        header("location: index.php");
    }
    else
    {
        $sql = "SELECT * FROM tbl_temp_members WHERE email='$email'";
        $res = mysql_query($sql);
        $count = mysql_num_rows($res);
        if($count==1)
        {
            echo "Login unsuccessful,Account still not activated";  
        }
        else
        {
            echo "Login unsccessful";
        }
    }
}

Location and Refresh both require an absolute URI (and it's "Location" instead of "location").

Try this one:

header('Location: http://absolute.uri/file.ext');

If that does not help, check my answer for any "strange" PHP problem ;)

(1) you don't need the refresh header if you have the location one

(2) add exit; in the end

The second special case is the "Location:" header. Not only does it send this header back to the browser, but it also returns a REDIRECT (302) status code to the browser unless the 201 or a 3xx status code has already been set.

<?php
header("Location: http://www.example.com/"); /* Redirect browser */

/* Make sure that code below does not get executed when we redirect. */
exit;
?>

Depends on what you are trying to do. Are you trying to cause a redirect ? If this is the case you could simply use header('Location: http://www.example.com/'); but if you want to refresh after a certain amount of time you can use:

header( "refresh:5;url=wherever.php" ); 
echo 'You\'ll be redirected in about 5 secs. ';
echo 'If not, click <a href="wherever.php">here</a>.';

Got the example code from - http://php.net/manual/en/function.header.php - maybe worth a read too.
