Mysql/Php - 当前日期和时间

Question

我有一个查询,我想用当前日期时间更新列.我想要更新的列是datetime类型.

我怎样才能得到它并设置它？

else{ //If the last update is NULL, It must be players first page load. So set datetime equal to NOW
    $query = "UPDATE `stats` SET `last_ap_update` =    WHERE `member_id` = {$_SESSION['SESS_MEMBER_ID']}"; 
    $queryresult = mysql_query($insertqry);
}

Answer 1

NOW()在查询中使用将提供此功能.

else{ //If the last update is NULL, It must be players first page load. So set datetime equal to NOW
    $query = "UPDATE `stats` SET `last_ap_update` =  NOW()  WHERE `member_id` = {$_SESSION['SESS_MEMBER_ID']}"; 
    $queryresult = mysql_query($insertqry);
}

但是如果在表更新时随时更新,我建议将列更改为,TIMESTAMP并且只要记录发生更改,这将自动更新为当前时间.

Answer 2

else{ //If the last update is NULL, It must be players first page load. So set datetime equal to NOW
    $query = "UPDATE `stats` SET `last_ap_update` =  '".gmdate("Y-m-d H:i:s")."'  WHERE `member_id` = {$_SESSION['SESS_MEMBER_ID']}"; 
    $queryresult = mysql_query($insertqry);
}

您可以使用任何您想要的格式而不是 gmdate("Y-m-d H:i:s")
