run php script in background centos server

Question

I want my php file to run in background. When I googled, I found that exec() is used to run in background. I am using a CentOS server. So, in order to use exec, what are all the basic things I should install? I don't even know how to run in terminal. What steps should I follow to run a php script in background using exec()?

I found this example on Google, but I don't know what to use in $cmd.

function execInBackground($cmd) { 
    if (substr(php_uname(), 0, 7) == "Windows"){ 
        pclose(popen("start /B ". $cmd, "r"));  
    } 
    else { 
        exec($cmd . " > /dev/null &");   
    } 
}

You can use nohup in your terminal:

nohup php my-file.php

Your PHP script will keep running even after you logout.

The other option is screen.

screen -A -m -d -S whatever ./phplauncher.sh
