Java implements timed tasks typically using a timer, or using the quartz component. Now the spring boot provides a more convenient way to implement it.Spring boot has integrated the scheduled tasks. Use @secheduled annotations.@Component//Enable Scheduled Tasks@EnableScheduling Public classTagpushscheduler {Private StaticLogger log = Logger.getlogger (Tagpushscheduler.class); @

I found some methods on the Internet to execute PHP scheduled tasks in WINDOWS. one of them was completely written, but unfortunately I did not pass it. Finally, I had to combine the methods of various schools in order to run successfully here. 1. write a PHP program named test. php. the content is as follows:
The code is as follows:
$ Fp = fopen ("test.txt", "a + ");
Fwrite ($ fp, date ("Y-m-d H: I: s"). "success! \ N ");
Fclose ($ fp );

To implement scheduler task control in PHP, you need to control the scheduler task list in the PHP script. the function is as follows: set five files that need to be scheduled to run regularly (can be added, deleted, or modified). These five files run through a php file plan. php control, and then use the linux crontab to directly run this plan. PHP file to achie
