Question

Can anyone tell me why I keep getting the else and alert is not being triggered at all? The cookie is being set just while the browser is open.

<?php
$setcookie = setcookie('version', 'nova');
$browser = get_browser(null, true);
    if(!isset($setcookie)){
        if($browser["MSIE"] < 8.0){
        // display message or alert!

               echo "<script language=\"JavaScript\">\n"; 
               echo 'alert("Please upgrade to version 8.0+ in order to view this site.");';
               echo "</script>";
        }
       }

        else

        {
            echo "Browser is current:";
        }

?>

Answer 1

Your if condition is wrong. You want to check the $_COOKIE array, not the return value of setcookie.

if(!isset($_COOKIE['version'])) {
  ...
}
