Sort of.
I don't think you need anything as fancy as a Socket to do what you want.
Just:
http://php.net/filemtime on the directory to detect contents changed
http://php.net/opendir and readdir to see what's in it
http://php.net/clearstatcache to make PHP forget cached status of the above
http://php.net/mail to send whatever emails you want
An infinite loop with http://php.net/sleep to do this every few seconds.
You'd maybe want to use http://php.net/pcntl to respond to system signals...
You'd maybe want to store the current filemtime and "current" directory
contents in a database or file so you'd be able to start/stop your process
and still send every email for all changes, even the ones that happen
while your program wasn't running.
You could maybe launch it from the shell with "nohup" to NOT get killed,
as I sort of understand it... Better read "man nohup" I think...
Assuming it's RedHat or similar, you'd want to write a /etc/rc.d/init.d
shell script to start/stop the PHP script.
I dunno where you thought you'd want a Socket in all this. [shrug] Maybe
I'm missing something...
Or did you want to have it respond to requests for info about a specific
directory?
Perhaps what you REALLY want is another process that listens on a Socket
to register the email has an "interest" in a specific directory. But you
could do that in a web FORM just as easily. Then your program above would
run through all the email/directory combinations and do its thing in a
more granular manner.
