setcookie(name, value, expire, path, domain);
推荐答案
您想对Cookie做什么？如果要从请求到请求跟踪服务器上的信息，则可能要使用会话，它会自动使用cookie。
What do you want to do with your cookie? If you want to track information on the server from request-to-request, you probably want to use a session, which automatically uses cookies.
否则，请继续使用 setcookie 以获得应用程序需要其他功能的Cookie。请注意PHP手册中的以下代码段：
Otherwise, go ahead and use setcookie for cookies that your application needs for other functionality. Pay attention to this snippet from the PHP manual:
setcookie（）将cookie定义为
以及其余的cookie HTTP
标头。像其他标头一样，必须在脚本
的任何输出之前发送cookie
（这是协议
的限制）。这要求您在
任何输出（包括和
标签以及任何空格）之前，先
对该函数进行调用。
setcookie() defines a cookie to be sent along with the rest of the HTTP headers. Like other headers, cookies must be sent before any output from your script (this is a protocol restriction). This requires that you place calls to this function prior to any output, including and tags as well as any whitespace.
<?php setcookie("cookiename", uniqid()); ?>
