|
11
|
|
|
* Note: |
|
12
|
|
|
* 1. Format: $timePeriods = [[$startDatetime1, $endDatetime1], [$startDatetime2, $endDatetime2], ...]; |
|
13
|
|
|
* - $Datetime = Y-m-d H:i:s ; Y-m-d H:i:00 ; Y-m-d H:00:00 ; |
|
14
|
|
|
* 2. If it is hour/minute/second, the end point is usually not included, for example, 8 o'clock to 9 o'clock is 1 hour. |
|
15
|
|
|
* - ●=====○ |
|
16
|
|
|
* 3. If it is a day/month/year, it usually includes an end point, for example, January to March is 3 months. |
|
17
|
|
|
* - ●=====● |
|
18
|
|
|
* 4. When processing, assume that the $timePeriods format is correct. If necessary, you need to call the verification function to verify the data. |
|
19
|
|
|
* 5. Ensure performance by keeping the $timePeriods format correct: |
|
20
|
|
|
* - a. When getting the raw $timePeriods, sort out it by format(), filter(), union(). |
|
21
|
|
|
* - b. Handle $timePeriods using only the functions provided by TimePeriodHelper (Will not break the format, sort) |
|
22
|
|
|
* - c. When you achieve the two operations described above, you can turn off auto sort out (TimePeriodHelper::setSortOut(false)) to improve performance. |
