Stopping and Starting Apache Using PHP (!)

I have two problem开发者_如何学Gos which are related.

1) I have a batch file that contains this:

net stop wampapache
net start wampapache

Which tries to stop and start my wamp server. When I double click the stop.bat file with the above it works successfully. When I try to run that from my PHP script, it stops the server but doesn't start it fully which I am guessing is because Apache is waiting for that PHP process to exit?

function php_kill(){

    exec('stop.bat', $output = array(), $return);

    return $return;

}

2) Is there a way to restart my webserver (apache) whilst keeping session variables that PHP needs available?

Thanks all

The PHP process is killing a process that, in turn, kills the PHP process. It's like going back in time and murdering your parents before they gave birth to you. I don't see how it can work.

One has to ask why this functionality is necessary. If you must do it this way, you should look into scheduling a service restart from the script. I don't know if this is possible via PHP and Windows.

The problem is related to the fact that exec waits for the process to end, but the process actually kills PHP so the whole thing gets stuck.

Running stop.bat as a background process should fix it. (here how to run a background process on Windows)
