Try using nohup before your command.

nohup catches the hangup signal while the ampersand doesn't (except the shell is confgured that way or doesn't send SIGHUP at all).

Normally, when running a command using & and exiting the shell afterwards, the shell will terminate the sub-command with the hangup signal (kill -SIGHUP ). This can be prevented using nohup, as it catches the signal and ignores it so that it never reaches the actual application.

In case you're using bash, you can use the command shopt | grep hupon to find out whether your shell sends SIGHUP to its child processes or not. If it is off, processes won't be terminated, as it seems to be the case for you.

There are cases where nohup does not work, for example when the process you start reconnects the NOHUP signal.

nohup php -f 'yourscript'.php
