password_verify
(PHP 5 >= 5.5.0, PHP 7, PHP 8)
password_verify — Verifies that a password matches a hash
Descrizione
$password, string $hash): boolVerifies that the given hash matches the given password. password_verify() is compatible with crypt(). Therefore, password hashes created by crypt() can be used with password_verify().
Note that password_hash() returns the algorithm, cost and salt as part of the returned hash. Therefore, all information that's needed to verify the hash is included in it. This allows the verify function to verify the hash without needing separate storage for the salt or algorithm information.
This function is safe against timing attacks.
