php中setcookie() 函数用法介绍
setcookie() 函数是php中一个用来设置cookie值的一个函数,下面我来总结一下setcookie() 函数的具体用法以及设置之后怎么获取cookie的值。
setcookie() 函数向客户端发送一个 HTTP cookie。
cookie 是由服务器发送到浏览器的变量。cookie 通常是服务器嵌入到用户计算机中的小文本文件。每当计算机通过浏览器请求一个页面,就会发送这个 cookie。
cookie 的名称指定为相同名称的变量。例如,如果被发送的 cookie 名为 "name",会自动创建名为 $user 的变量,包含 cookie 的值。
必须在任何其他输出发送前对 cookie 进行赋值。
如果成功,则该函数返回 true,否则返回 false。
语法
setcookie(name,value,expire,path,domain,secure)
例

makecookie('111','www.bKjia.c0m'); //下面兴一个支持二级域名cookie函数吧。 function setcookielive($name, $value='', $expire=0, $path='', $domain='', $secure=false, $httponly=false) { setcookielive('webab','111cn',time()+86000,'/','bKjia.c0m'); //一入门级cookie设置方法 setcookie("cookie[three]", "cookiethree"); // after the page reloads, print them out |
