Assuming a typical LAMP system, you can start a PHP daemon from the command line with

root# php yourscript.php &

where yourscript.php contains something similar to

Embellishments: To make your script directly executable: chmod +x yourscript.php and add #!/usr/bin/php to the beginning of yourscript

To start with apache, you should add that command to your apache startup script (usually apachectl) and be sure to add code to kill it when apache stops.

The check if you are already running involves a file with your PID in /var/locks/ and something like system('/bin/ps '.$thePID); It also makes the kill instruction easier to write.
