it works.
<?php
session_start();
if (!isset($_SESSION['count'])) {
$_SESSION['count'] = 1;
}
else {
$_SESSION['count']++;
}
echo $count;
?>
but the first time,i also get the warning(Warning: Undefined variable:
count in C:\WebShare\wwwroot\netk\5\test.php on line 9
).then ,it outputs 2(3,4.....)
can you tell me why it beheave like that?
thanks.
