Hy!
iam going to decide to SHA_512 with salt in my web project.
ut iam still in confiusion that there is some problem in it..
the hashing algorithm just hash the data before saving it in to the database something like ( 45454dsdsd54d4sd ).
how can the admin know about the user password?
how can he access to his personal data/profile?

if there is anothr way to secure the user input data in web please tell me...

Design the system in such a way that admin can access the user data other than the password...The password should be hashed and should not be available to any other person than the user

No admin in the world is supposed to get access to a user password; and it is never needed; thinking a password can be accessed means total misunderstanding of the very basic idea of the password-based authentication.

For further detail, please see my past answers:

With PHP, please start here: http://php.net/manual/en/function.hash.php[^].
