Setting proc title on PHP based daemons is pretty sweet.

In Windows, this function will set the Command Prompt window title, which is restored to the previous setting once the script finishes. If you need to do this in 5.5.X and below, you'll need to use system() to run the title command.

Please note that the function might be inconsistent depending on your system.
On 2 of my systems (CentOS 7.7 and Linux Mint 18.3), setting the title will work for ps but not for top.
<?php
cli_set_process_title("sleeping-daemon");
sleep(100);
/*
 *ps* returns
25072 pts/2 S 0:00  sleeping-daemon
*top* returns
25072 aurelien 20  0 285848 23256 16856 S  0.0 0.3  0:00.01 php
*/

Beware that if you kill the process via console the original command line will appear.
