虽然您以纪元时间戳格式存储日期时间,但我认为使用 MySQL 日期/时间函数的解决方案可能会非常慢。所以,我建议像下面的代码一样使用时间戳本身。
使用示例
$t = time();
# today
echo date('Y-m-d H:i:s', strtotime('today', $t))."\n";
echo date('Y-m-d H:i:s', strtotime('tomorrow', $t))."\n";
# this week
echo date('Y-m-d H:i:s', strtotime('-1 sunday', $t))."\n";
echo date('Y-m-d H:i:s', strtotime('sunday', $t))."\n";
# this month
echo date('Y-m-d H:i:s', strtotime(date('Y-m-01 00:00:00', $t)))."\n";
echo date('Y-m-d H:i:s', strtotime(date('Y-m-01 00:00:00', strtotime('next month', $t))))."\n";
# this year
echo date('Y-m-d H:i:s', strtotime(date('Y-01-01 00:00:00', $t)))."\n";
echo date('Y-m-d H:i:s', strtotime(date('Y-01-01 00:00:00', strtotime('next year', $t))))."\n";
查询中
# this year
$start_of_year = strtotime(date('Y-01-01 00:00:00', $t));
$end_of_year = strtotime(date('Y-01-01 00:00:00', strtotime('next year', $t)));
$query = "SELECT * FROM sometable WHERE somecolumn >= $start_of_year AND somecolumn < $end_of_year";
