I am still having problems with the regular expressions. Looks like there 
has been a change in the way they are handled between PHP3 and PHP4, since 
the code worked with PHP3 !!

I need to search for all words having alphanumberic characters as well as _ 
(underscore) which are prefixed and suffixed with __ (2 underscores).

The regular expression I am using is
eregi("__([a-z0-9_]+)__", "Hello __WO_RD__ Test", $Matches)

I am expecting the above code to return __WO_RD__ as the match, but it does 
not seem to work. Can someone help out.

With Regards,
