I was trying the "$_SESSION" function, but it didn't work. Here are the codes.
test1.php
<?php
session_start();
$_SESSION['testid']= "12";
?>
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Test Page</title>
</head>
<body>
<h1><?php echo $_SESSION['testid']; ?></h1>
</body>
</html>
The output was:
12
test2.php
<?php
session_start();
?>
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Test Page 2</title>
</head>
<body>
<h1><?php echo $_SESSION['testid']; ?></h1>
</body>
</html>
The output was nothing.
So, what is the problem?
