PHP 讀寫cookie的語句: javascript
setcookie("user", "Lilu", time()+3600); echo $_COOKIE["user"];
function SetCookie(name,value)//兩個參數,一個是cookie的名子,一個是值 { var Days = 30; //此 cookie 將被保存 30 天 var exp = new Date(); //new Date("December 31, 9998"); exp.setTime(exp.getTime() + Days*24*60*60*1000); document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString(); } function getCookie(name)//取cookies函數 { var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)")); if(arr != null) return unescape(arr[2]); return null; } function delCookie(name)//刪除cookie { var exp = new Date(); exp.setTime(exp.getTime() - 1); var cval=getCookie(name); if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString(); } SetCookie ("lilu", "it's me") alert(getCookie('lilu'));
頁面用不一樣的瀏覽器訪問cookie就存放在不一樣的地方,好比IE瀏覽器的cookie存放在
C:\Users\[your computer name]\AppData\Roaming\Microsoft\Windows\Cookies php
在同一瀏覽器下 javascript產生的cookie和php產生的cookie能夠互相訪問好比: java
alert(getCookie('user'));
echo $_COOKIE["lilu"];
