How PHP executes code at intervals

This example describes how PHP executes code at intervals. Share it with everyone for your reference. The specific analysis is as follows:

How to set up PHP to automatically execute a certain piece of code every period of time? For example, to generate static files regularly, this requires setting a sleep time, that is, the program will call a certain piece of code every once in a while.

The code is as follows:

Copy the code as follows:ignore_user_abort(); //Even if the Client is disconnected (such as closing the browser), the PHP script can continue to execute.

Set_time_limit(0); // The execution time is unlimited. The default execution time of PHP is 30 seconds, which allows the program to execute without limit.

　$interval=24*60*60; // Run every other day

do{

　sleep($interval); // Wait for one hour according to the set time and execute the loop

$sql="update blog set time=now()";

　...... //Other operations

　}while(true);

I hope this article will be helpful to everyone’s PHP programming design.
