PHP & MySQL compare password

Question

How does one check to see if a user has typed in the right password to log in?

This is what (out of a bunch of combinations...) I am doing:

Answer 1

Get password from user from FORM POST method and convert $_POST['password'] //from form// into appropriate format in php/jsp/any other then compare with formatted password in your database

Generally md5 encryption is used whene you can compare md45('{$_POST['password']}')= present in your db; or generally mysql use password('your password') command while creating password hence first concert your $_POST['password'] into mysqli_query and mysqli_fetch_array to get encrypted password value and then compare.
