It doesn't, but if you use double quotes you need to escape twice (once
for the php parser and once to tell ereg its really the dollar sign and
not an end-of-line metacharacter):

  $version = ereg_replace("\\\$", "", '$Revision: 1.8 $');

or use single quotes:

  $version = ereg_replace('\$', "", '$Revision: 1.8 $');

Ciao,
