Static class variables

[Anon]

in php can you create a class that has a static variable?

for example, I have two scripts running, one script is relying on the other script to finish writing to a file. Instead of running a while loop with file_exists() (which seems to be very expensive), I'd rather have a class with a static variable that I can use as the lock key.

any idea?

Thanks,

What is the scope of these two scripts?

The scripts are in two seperate files, so they have zero scope i guess. Is there a way for two seperate scripts to share a variable or send a variable to the other script?

Thanks,
