改成
<?php
session_start();
?>
<html>
<head><title>test.php</title></head>
<body>
<?php
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
if (!isset($_SESSION['count'])) {
$_SESSION['count'] = 0;
echo("count has not set before");
} else {
$_SESSION['count']++;
echo("count has already set.");
}
echo($_SESSION['count']);
?>
</body>
</html>
然后,你在PHP的目录下建立一个tmp这样的目录.
应该就可以了.Top
