Header() is not redirecting PHP [closed]

Answer 1

Try formatting the header correctly:

header("Location: login.php?msg=Please+Login+Again.");

And of course make sure that you are not sending any output (either on purpose or by mistake) before the call.

Answer 2

If you're using header("Location: "); after you've output content make sure you've put ob_start(); earlier in the script. ob_start(); buffers your script, so nothing is output until you either call ob_end(); or the end of the file is reached. Calling header("Location: "); after content has already been output to the browser can cause problems.

Answer 3

Make sure to put an exit; or die; after the command: and make the "Location" start with uppercase

if (!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '') AND !isset($fb_login)) {           
    header("Location:login.php?msg=Please+Login+Again.");
    exit;
}

Answer 4

Adding to what others have said, are you sure that the cnditions are met to hit the header()

You could use empty() to clear up your code & Do some testing :

//Debug
unset($_SESSION['SESS_MEMBER_ID']);
unset($fb_login);

if(empty($_SESSION['SESS_MEMBER_ID']) && !isset($fb_login)) {
    exit(header("Location: login.php?msg=Please+Login+Again."));
}

Answer 5

Put ob_start(); in beginning of PHP file , it will helps,

<?php
    ob_start();
    /*
    Your code
    */
 ?>

Answer 6

1) Be sure that you do not send anything before the header() function
