php簽到功能的實(shí)現(xiàn)方法：首先在數(shù)據(jù)庫(kù)里建兩張表，一個(gè)是用戶的積分表，一個(gè)是簽到狀態(tài)表；然后通過(guò)時(shí)間戳的判斷，及時(shí)更新?tīng)顟B(tài)表；最后根據(jù)上次簽到時(shí)間和這次簽到時(shí)間進(jìn)行比較判斷有沒(méi)有漏簽和今日是否已簽到即可。

首先我在數(shù)據(jù)庫(kù)里建了兩張表,一個(gè)是用戶的積分表,一個(gè)是簽到狀態(tài)表,分來(lái)用來(lái)記錄用戶的積分?jǐn)?shù)和先到狀態(tài)

在用戶簽到狀態(tài)表中我們有一個(gè)字段,last_sign_time,即上一次簽到時(shí)間,每次可以簽到的時(shí)候把這個(gè)時(shí)間與當(dāng)前時(shí)間進(jìn)行比較 如果相差為0天,則說(shuō)明今天已簽到(這個(gè)簽到是24小時(shí)內(nèi)只能簽到一次,即兩次簽到時(shí)間要相差24小時(shí)以上).如果等于一天則今日可以簽到,如果2天及其以上則說(shuō)明漏簽了.

通過(guò)時(shí)間戳的判斷,及時(shí)更新?tīng)顟B(tài)表,并且當(dāng)可以簽到的時(shí)候則對(duì)用戶積分表進(jìn)行操作,即更新用戶積分.
