PHP implementation close remote computer _php tutorial

There are many ways to implement a remote computer, and here's how to extract a shutdown command description if you shut down a remote Windows computer

The shutdown command syntax format is: shutdown [-i |-l|-s |-r |-a] [-f] [-M [\ComputerName]] [-t-XX] [-C "message"] [-d[p]:xx:yy].

"-I" displays a dialog box for the graphical interface.

"-L" unregisters the current user, which is the default setting.

"-S" shuts down the computer.

"-R" is turned off and then restarted.

"-A" abort shutdown.

"-F" forces the application to be shut down.

"-M [\computername] Specifies the computer to be shut down.

"-T-XX" Sets the timer for system shutdown to xx seconds, and the default value is 20 seconds.

"-C" message "Specifies the message that will be displayed in the messages area of the system Shutdown window, with a maximum of 127 characters, and must contain a message in quotation marks.

"-d [p]:xx:yy] lists the reason codes for system shutdown.

In addition to "-L" and "ComputerName", the system ignores other parameters. Only "-a" can be used during the time-out period.

For example, turning off the remote computer input "shutdown-s-m \work1-t 60" means that after 60 seconds the machine named work is turned off, and the machine must also have a Windows XP operating system. The input "shutdown-s-T 30" means that the machine shuts down automatically after 30 seconds. "Shutdown-l" means to unregister the native user, which does not apply to the remote computer. Use "Shutdown-r" to restart the local computer. "Shutdown-a" can cancel an already issued shutdown command. You can use "Shutdown-s" when you want to shut down the local computer.

In PHP, System and exec can perform shutdown commands, and if the remote computer's hardware and software configuration meets the following criteria: Grant the Guest user permission to remotely shut down the machine. When a remote user connects to a local Windows XP system that is connected as guest, the remote shutdown requires administrator privileges, so the guest user is given permission to remotely shut down the computer. Start the computer that requires a remote shutdown, enter gpedit.msc in the Run dialog box, and open the Group Policy Editor. Expand Computer Configuration → Windows settings → security settings → local policies → user rights Assignment, locate the force shutdown from remote system option in the right window. Double-click the item, in the Pop-up dialog box, by clicking the Add button, and then entering the user name "Guest" in the new dialog box, and then clicking OK. Now that the "guest" user is in the "Force shutdown from remote system" attribute, click the "OK" button to exit.

Code:

System (Shutdown-s-M \work1-t 60);
?>
