Are there best practices for securely storing and validating passwords in PHP, considering the issues raised in the forum thread regarding changing hash values?

Issue: Changing hash values for password storage can create security vulnerabilities if not handled properly. Best practices for securely storing and validating passwords in PHP include using a strong hashing algorithm like bcrypt, salting passwords before hashing, and periodically updating the hashing algorithm as needed. 

// Storing a password securely
$password = "secret_password";
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Validating a password
$entered_password = "secret_password";
if (password_verify($entered_password, $hashed_password)) {
    echo "Password is valid!";
} else {
    echo "Invalid password.";
}
