I’ve a problem when use this code in my page:

Code with expire session

<?php 
session_start();
if(!isset($_SESSION['clientmacs']) ) { 
    header('Location: index.php');
} else {
    if(time() - $_SESSION['timeLogin'] > 1800) {
        header('Location: include/logout.php');
    }
    $userclient = $_SESSION['clientmacs'];
?>
<html>
    HTML CODE
</html>
<?php
}
?>

But if I use this code the problem disappears and the page works normally:

Code without expire session

<?php 
session_start();
if(!isset($_SESSION['clientmacs'])) { 
    header('Location: index.php');
} else {
    $userclient = $_SESSION['client'];;
?>
<html>
    HTML CODE
</html>
<?php
}
?>

Error in Google Chrome:

This webpage has a redirect loop

Http://localhost/mac/index.php The website has too many redirects. The incidence may be
resolved by deleting the cookies from this site or allowing third party cookies. If
that fails, the incidence may be related to a bug in the server configuration, not the
computer.

    You need to reset the $_SESSION value for timeout ($_SESSION[‘timeLogin’]) when you execute redirection, otherwise when the client is back from redirect the value in session is the same and will be again redirected.

    You could solve it with:

    if(!isset($_SESSION['clientmacs']) ) {
    $_SESSION['clientmacs'] = ""; // add this line if not added somewhere else
    header('Location: index.php');
}

    and

    if(time() - $_SESSION['timeLogin'] > 1800) {
    $_SESSION['timeLogin'] = time(); // add this line
    header('Location: include/logout.php');
}

    Maybe (depending on your logic) is better clear the entire session, and let it be reconfigured through the normal flow (session_destroy()) when you perform redirect.
