You can probably use a static variable.
You can increment a static variable as a counter, and it will
remember its value between iterations of the php program.
(Sideline Suggestion: when making a cookbook recipe, try to name
variables with a prefix for your recipe: $mine_variable)
(From the PHP manual)
Example 12-6. Example use of static variables
static $a = 0;
Now, every time the Test() function is called it will print the value
of $a and increment it.
(end PHP manual quote)
I don't know a lot about it, but from what I do know, these variables
can be used for web page counters, and that implies they should work
for your purposes. After that I imagine you would have to unset()
the variable to reset it every year, so add in a isNewYear() function
returns true if there are no files prefixed with the current year,
and unset the variable in an if(isNewYear()) statement before the
declaration...or however you decide to handle it.

considered myself German intellectually, until I noticed the growth
of anti-Semitic prejudice in Germany and German Austria. Since that
time, I prefer to call myself a Jew.
