'PHP exec 'VBoxManage startvm'

I'm trying to start virtualbox machine throught PHP script on server. I wrote this script:

<?php
    echo(exec("sudo VBoxManage startvm 'EnterToJa'"));
?>

And it runs on server, but it waits only for first line: 

Waiting for VM "EnterToJa" to power on...

After that it probably kills it. When I run that VBoxManage command on my server from terminal it works, but I have to wait ~5 seconds and I this that is the problem.

P.S.
www-data <- has got permission to run sudo without password

Solution 1:[1]

To make your VirtualBox work you have to add into your command line |at now.

Example:

<?php
    exec("sudo VBoxManage startvm 'EnterToJak' --type HeadLess|at now");
?>

Solution 2:[2]

Running this command in background should help in your case.

This should help:

   exec("sudo VBoxManage startvm 'EnterToJa' &");
