First of all, I just started PHP. I know my methods might not be the most efficient, but please try to remember that I’m new to all of this. Examples work great.
I’m trying to write a simple php code for that asks the user three questions. One true/false, one multiple choice and one short answer. Each question is displayed on its own page.
When I try to run this, I get the following error:
Error: Deprecated: Function session_is_registered() is deprecated on line 10
This script still runs with this error. The problem though is at the end of the quiz, the variable $correct does not seem to change. I printed the variable to see if it was changing and nothing gets printed so obviously something is wrong — possibly the deprecated function error is the culprit.
Any help would be appreciated.
<?php
ini_set('session.gc_maxlifetime',900);
//echo ini_get("session.gc_maxlifetime");
session_start();
if($_SESSION['loggedin'] !== 1) {
header('Location: login.php');
exit;
}
if (!session_is_registered("loggedin"))
{
$_SESSION["number"] = 0;
$_SESSION["correct"] = 0;
}
$total_number = 3;
print <<<TOP
