Ruby password SHA512 hash replication using PHP

is there any way I can reproduce this ruby function:

def Password.hash(password,salt)
    Digest::SHA512.hexdigest("#{password}:#{salt}"开发者_StackOverflow)
end

In php.

Cheers

Something like this should do it, using the php hash() function

function passwordhash($password, $salt)
{
   return hash('sha512', "{$password}:{$salt}");
}
