Hi,I am new to PHP, I practised PHP setcookie() just now and failed.
http://localhost/test/index.php
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
</head>
<body>
<?php
$value = 'something from somewhere';
setcookie("TestCookie", $value);
?>
</body>
</html>
http://localhost/test/view.php
<?php
// I plan to view the cookie value via view.php
echo $_COOKIE["TestCookie"];
?>
But I failed to run index.php, IE warning like this.
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\test\index.php:9) in C:\xampp\htdocs\test\index.php on line 12
I enabled my IE 6 cookie no doubt.
Is there anything wrong on my procedure above? Thank you.
