PHPsetcookie设置Cookie用法(及设置无效的问题)_PHP教程

Warning: Cannot modify header information – headers already sent by (output started at C:\xampp\htdocs\b.php:2) in … on line … 
 
但因为当时php.ini设置成了error_reporting = E_ALL & ~E_NOTICE，于是没有任何提示，所以开发的时候还是建议设成error_reporting = E_ALL 方便观察到一些异常情况。 

附一个setcookie用法实例 
a.php 
 代码如下:

setcookie("page", "a.php"); 
$page = $_COOKIE["page"] ? $_COOKIE["page"] : "unknown"; 
echo "From " . $page . "

"; 
?> 
This is a.php. Go to b.php 
 
b.php 
 代码如下:

setcookie("page", "b.php"); 
$page = isset($_COOKIE["page"]) ? $_COOKIE["page"] : "unknown"; 
echo "From " . $page . "

"; 
?> 
This is b.php. Go to a.php
