How can I decrypt a password hash in PHP?

I need to decrypt a password. The password is crypted with password_hash function.

$password = 'examplepassword';
$crypted = password_hash($password, PASSWORD_DEFAULT);

Now, let's assume that $crypted is stored in a database (there's a "users" table, with usernames, passwords, etc) and I need to do a login: I have to see if the password entered by the user matches the crypted password stored in the database.

This is the sql code...

$sql_script = 'select * from USERS where username="'.$username.'" and password="'.$inputpassword.'"';

...but $inputpassword is not crypted, so it's not equal to what is stored in the password field of the table users...

So, there's a function to decrypt after the use of password_hash? Or should I change my encrypt method? Or what else?
