Wordpress and Joomla hash and salt

I would like to know where the hash and salt are in Wordpress and Joomla hashes?

For example: In this wordpress hash

P$BTBCNLQpY5CWWQ6XC4WJ6IPJQ877s3 

where the salt is?

In this Joomla hash

$2y$10$io60pn4npWCRWwg4308pB.4rLmfz.vFwzxzYmX6W48Ff7wTi7ZEMO

where the salt is?

For example (source wikipedia), the bcrypt shadow password record

$2a$10$N9qo8uLOickgx2ZMRZoMyeIjZAgcfl7p92ldGxad68LJZdL17lhWy

specifies a cost parameter of 10, indicating 210 key expansion rounds. The salt is

N9qo8uLOickgx2ZMRZoMye 

and the resulting hash is

IjZAgcfl7p92ldGxad68LJZdL17lhWy

Thanks you.

Wordpress uses phpass, which handles salts internally and doesn't encode a separate salt in the output. I think the P$ just tells it what hash was used.
