It is actually very simple to determine whether it is morning or afternoon in PHP. In this article, we will show you how to use PHP to get whether the current time is AM or PM.
The function in PHP to get the current time is date(). Using this function, we can easily get the current hour, minute, second and other information. For example, the following line of code will output the current hour:
echo date('H');
For the time format, H represents the hour in 24-hour format, such as 00 to 23; h represents the hour in 12-hour format, such as 01 to 12.
So how to determine whether it is morning or afternoon based on the current hour? In fact, it is very simple. We only need to determine whether the current hour is less than 12. If it is less than 12, it belongs to the morning, and if it is greater than or equal to 12, it belongs to the afternoon.
The following code can achieve this function:
$hour = date('H');
$am_pm = ($hour < 12) ? "上午" : "下午";
echo "现在是".$am_pm;
This code will get the current hour and then determine whether it is less than 12. If so, the value of the $am_pm variable is "AM", otherwise the value is "PM". Finally, this value is output to the page.
The above code is very simple, but sufficient to meet the requirements of most scenarios. If you need to make more precise judgments, for example, each hour segment has a different title, you can modify it according to your needs.
To sum up, it is very simple to determine whether it is morning or afternoon in PHP. You only need to use the date() function to get the current hour and determine whether it is less than 12. This method is simple and crude, but it is enough to meet most needs. If you need more precise judgment, you can modify it according to your needs.
