Php 从数据库时间戳中提取详细信息

我正在学习时间戳。我可以找到很多关于从当前时间戳中提取数据的信息，但很少有关于查询数据库时间戳的信息。例如，我想执行以下操作（语法不正确，但希望能说明我的问题）

你能告诉我正确的方向吗？

你可以使用MySQL函数。

SELECT * FROM database WHERE DAY(FROM_UNIXTIME(timestamp)) = 12 
    AND MONTH(FROM_UNIXTIME(timestamp)) = 1

SELECT * FROM database WHERE MONTH(FROM_UNIXTIME(timestamp)) = 1
    AND YEAR(FROM_UNIXTIME(timestamp)) = 2009

对于第二种方法，更有效的方法如下：

SELECT *
FROM database
WHERE timestamp BETWEEN
    UNIX_TIMESTAMP('2009-01-01 00:00:00')
    AND
    UNIX_TIMESTAMP('2009-01-31 23:59:59')

SELECT * FROM database WHERE DAY(FROM_UNIXTIME(timestamp)) = 12 
    AND MONTH(FROM_UNIXTIME(timestamp)) = 1

SELECT * FROM database WHERE MONTH(FROM_UNIXTIME(timestamp)) = 1
    AND YEAR(FROM_UNIXTIME(timestamp)) = 2009

SELECT *
FROM database
WHERE timestamp BETWEEN
    UNIX_TIMESTAMP('2009-01-01 00:00:00')
    AND
    UNIX_TIMESTAMP('2009-01-31 23:59:59')
