20 views

To use password_verify in PHP, start by hashing the password with password_hash(). Then, to verify, use password_verify() with the user's input and the stored hash. For example: 1. $hash = password_hash('user_password', PASSWORD_DEFAULT); 2. if (password_verify('user_password', $hash)) { 3. // Password is correct 4. } else { 5. // Password is incorrect 6. } Password hashing ensures security by not storing plain-text passwords.**
