1，php设置与打印cookie值，代码：
<?php
setcookie( "myvalue1", "myvalue2", time()+3600, "/", "www.jb200.com", 0 );
?>
<html>
<head>
<title>设置与打印cookie的值--www.jb200.com</title>
</head>
<body>
<?php
if ( isset( $myvalue1 ) )
print "<p>Hello again, your value is $myvalue1</p>";
else
print "<p>Hello you. This may be your first visit</p>";
?>
</body>
</html>
2，创建一个测试cookie，用于体验php cookie的用法。
<?php $string_name = " testcookie"; $string_value = "This is a test cookie"; $expiry_info = time()+259200; $string_domain = "localhost.localdomain"; setcookie($string_name, $string_value, $expiry_info, $string_domain); ?>
3，使用多值cookie
<?php
if (!isset ($userdetails [0] ) ) {
setcookie ("userdetails[0]", $username);
}
$userdetails[1]++;
setcookie ("userdetails[1]", $userdetails[1]);
echo ("Hello $userdetails[0], you've seen this page".$userdetails[1].($userdetails[1] == l?" time!": "times!"));
?>
