how to use PHP to reboot the computer?

nideshuai

:o I have a task, i must use the php to reboot my
computer,but i really do not know how to do and
where to begin,would you like to give me some
advice or some clue?<waitong on line>

you would have to have the php running on the computer you want to reboot, ie as a php server or using command line php. there's a php function to access the command line, so you use this to run a cscript (see http://msdn.microsoft.com/scripting) which reboots the computer.

Try this if you're under Linux:

exec("shutdown -r")

the cicumstance is Redhat Linux 8.0+Apache1.3.27
+PHP4.2.3,i use the script exec("shutdown -r"),
but, the computer has no response,i am puzzled ,
i can use the exec( ) function to excute the command "ping","route" and so on,why i can't excute the command "shutdown -r"?

User "nobody" isn't authorized to reboot the computer.

nideshuai

:o i run apache with the account "apache" user and the "apache" group,the account is authorized to excute the command "shutdown",then excute the script <? exec ("/sbin/shutdown -r now",$list) ?>,but there is no response too. Does the PHP have the capacity of rebooting the computer? i am quite puzzled.
now help me again,thanks firstly.

try running the command using the [man]system[/man] call

system("shutdown -r &");

i haven't tried that, but it would be interesting to see the results

nideshuai

i try the script <? system("shutdown -r &") ?>
the result makes me disappointed again, i lose my hope,but i believe there is a will,there is a success.

are you running php in safe mode?

nideshuai

i have read php.ini,i find the safe_mode is off,so the
fact is not due to the php.ini configuration. do you think so? there must be the other cause.

neither nobody neither apache users should be able to reboot.
