A simple solution is

nohup php script.php &

So you run script in background and disconnect the process from the terminal. If it doesn't help, try disown command after it. There is a good answer with detailed explanation of differences between these commands.

To get full control of your script, a good choice would be a System V init script. There is a template at https://github.com/fhd/init-script-template, which you can use.

Copy template to /etc/init.d directory and rename it. In template you need to change variables:

dir="/your/working/directory"
cmd="nohup php script.php"
user="your user"

Doing that you will be able to control your script by

/etc/init.d/your_script start
/etc/init.d/your_script stop

Make sure you have permissions to write in /var/log/ and /var/run/, or run script as sudo(leave user="" empty)
