I have a php script that I can either run from the command line or as a Linux daemon.  I would like to create a conditional statement based on which way it is being run.  Ex:

If (needed function)
    echo("I'm running in daemon mode");
else echo{"I'm running in console mode");

I'm looking for the needed function to accomplish this from within the script.  thank you.

getopt() appears to be a very powerful function with unlimited options.  Would you happen to have an example with the correct parameters or options?

$options = getopt ("d");
$daemon_mode = isset ($options ["d"]);

So if you run your script with a -d parameter, $daemon_mode will be true. Otherwise it will be fails.

Sorry. My phone auto corrected incorrectly.

I thought that was it.  but when I try this code it always shows as false...  
The command I use to enter daemon mode is:  
PID=`$DAEMON > /dev/null 2>&1 & echo $!`  
Perhaps I could add a parameter to this command line?
