Mysql/Php - Current date and time
提问by user377419
I have a query that I want to update a column with the current date time. The column I want to update is of the type datetime.
我有一个查询，我想用当前日期时间更新一列。我要更新的列是日期时间类型。
How can I get it and set it?
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);
}

Using NOW()in the query would provide this.
NOW()在查询中使用将提供这一点。
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);
}
But if this gets updated anytime the table updates, I would suggest changing the column to TIMESTAMPand this will automatically update to the current time for you anytime that record changes.
但是，如果在表更新时随时更新，我建议将列更改为TIMESTAMP，这将在记录更改时自动更新为当前时间。

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);
}
You can use any format you want instead of gmdate("Y-m-d H:i:s")
您可以使用任何您想要的格式，而不是 gmdate("Y-m-d H:i:s")

You can use the mysql function NOW() for this, or you can pase the $_SERVER['REQUEST_TIME'] in there so the query gets cached by mysql.
您可以为此使用 mysql 函数 NOW()，或者您可以在其中传递 $_SERVER['REQUEST_TIME'] 以便查询被 mysql 缓存。
