How to determine the current time period in PHP?

To determine the time period of the day, you can use PHP’s time functions to get the current time and make the judgement. Here is an example code:

<?php
$current_time = strtotime(date('H:i')); // 获取当前时间的时间戳
$morning_start = strtotime('06:00'); // 早上开始时间
$noon_start = strtotime('12:00'); // 中午开始时间
$afternoon_start = strtotime('13:00'); // 下午开始时间
$evening_start = strtotime('18:00'); // 晚上开始时间

if ($current_time >= $morning_start && $current_time < $noon_start) {
    echo "早上";
} elseif ($current_time >= $noon_start && $current_time < $afternoon_start) {
    echo "中午";
} elseif ($current_time >= $afternoon_start && $current_time < $evening_start) {
    echo "下午";
} else {
    echo "晚上";
}
?>

In the above code, we use the strtotime function to convert a time string into a timestamp, and then use the date function to get the current time’s hour and minute parts. We then compare the timestamp of the current time with the timestamp of a predefined time period to determine which time period the current time falls into, and output the corresponding result.

Please note that the above code is just an example and you can define the start and end times of the time frame according to your own needs.
