shell_exec command question

pelegk2

i am running a shell_exec command whih runs this bacth file :
Code:
net stop apache2
net start apache2

the problem is that when i run it the stop command is executed but not the start command!
it seem's like the stop command kills the batch file that is working too!
what can i do?
thanks in advance

start /D [dir base path - path to batch file] /B [batch file command]

That will tell Windows to launch the app in a background process. I don't know if it will help with what you are doing. Shutting down Apache means you're shutting down PHP as well which means PHP may stop any child processes it has started.

If need be, you may need to have your batch file issue the "AT" command to schedule a task to run almost immediately (say 30 seconds) which then runs your batch program to stop/start Apache.

 shell_exec("start /B restart.bat");

it stoped as usuall and didnt start again 🙁

Yeah, try scheduling a task. I would bet that would work. The batch file would execute as a child of the task scheduler and NOT PHP and Apache. So when Apache goes down, it doesn't take PHP and its running children with it.

Your English is kind of out there. I'm not sure what you're trying to say.

Check out how the "at" command works on the command prompt of a Windows box (you'll need a server edition). It allows you to schedule a task from the command line (which is what you'll want to do). You don't need to forecast WHEN to actually have the task run, just schedule it so its 10-30 seconds in the future. It would be enough time to have PHP schedule the task and complete the steps to get that task scheduled before Apache shuts PHP down. You're still running the task when you want, but you're assigning the job of stopping/starting Apache to the task manager instead of just PHP (which gets shutdown when you shutdown Apache).

Yup - the "schedule thing".
