crypt question (search mail list) - Mailing list pgsql-sql

There was a post about a month ago about crypt and md5
fields being compared to text values...
(Can I search the archive... google lists... are these
the same as what we see here?)

Using PostgreSQL MD5 stored 'userpasswd' field with PHP 
 if(data[userpasswd] == md5(trypassword))

is never true, even when I substr the first 16 characters.
They appear the same if I print them! 

Is this something to do with unicode?
...how do I compare a string value with a unicode string?
