Check the current process or deadlock process, and automatically kill the dead process_PHP tutorial

/*--Handling deadlock
View the current process or deadlock process, and can automatically kill the dead process
Because it is for deadlock, so if there is a deadlock process, you can only view the deadlock process
Of course, you can control it through parameters. No matter whether there is a deadlock or not, you will only view the deadlock process
