分享代码基地会员中心的PHP签到系统，PHP很漂亮的签到界面。签到后，会有不同颜色区分。附带PHP签到源码带安装说明和详细注释。(详细查看https://www.daimajidi.com/deal/574)
JS:
```
function getUrl(strs) {
var url = "/demo/1563064903/" + strs;
return url;
}
function signDay(obj) {
$.post(getUrl("Ajax/signDay"), {}, function(data) {
if(data == -1){
alert("请登录！");return false;
}
var num = obj.find("span").text();
var td = "
\n\" + num + "
\n\已签到
obj.before(td);
obj.remove();
if (data > 0) {
alert("签到成功获取 " + data + " 积分");
} else {
alert("今天您已签到！");
}
})
}
```
