PHP obtains the timestamp of a certain time interval.

In the past two days, we need to implement the following functions:

When a certain condition is reached, the server sends a text message to the user. The number of messages is multiple.

Basic Idea: scheduled linux scanning. If a user meets the requirements, the user will send a text message.

However, to prevent disturbing users, you must send text messages between-during the day. How can you get the daily time range?

Copy codeThe Code is as follows:
$ Y = date ("Y", time ());
$ M = date ("m", time ());
$ D = date ("d", time ());
$ Start_time = mktime (9, 0, 0, $ m, $ d, $ y );
$ End_time = mktime (19, 0, 0, $ m, $ d, $ y );

$ Time = time ();
If ($ time >=$ start_time & $ time <= $ end_time)
{
// Do something ....
}
