[PHP] Possible to write CRC/MD5 to the file?

[Simon Fredriksson]

I wonder if it's possible to write the MD5 or CRC checksum of my 
scriptfile to the scriptfile. I know that if I change it, the value will 
change, but is there any way to calculate what it will be?

Not just displaying it for the user, but actually having it written in 
the file. Could be pretty usefull when distributing scripts. No worries 
about losing the md5-file or sfv, etc.

Just some thoughts.
