nohup on windows, exec without waiting for finish

Question

Is there something like this for Windows?

exec(\"nohup /usr/bin/php -f sleep.php > /dev/null 2>&1 &\");

Answer 1

By default, the Windows command start does not wait for the child process. You may want the /b switch to avoid creating a Command Prompt window.

exec("start /b c:\\php\\php.exe -f sleep.php");
