Where Should Password Verification Be Placed in a Login Script?

Where to Integrate Password Verification in a Login Script

In a login script, the password is typically entered by the user and stored in a clear text variable. To verify the entered password against the encrypted password stored in the database, we need to use password_verify().

if(password_verify($enteredPassword, $hashedPassword)) {
    // Password verification successful
} else {
    // Password verification failed
}

Integrating Password Verification in Your Login Script

In your specific case, you can integrate password_verify() in the following code segment:

if(($row = $query->fetch()) && (password_verify($ctPassword,$row['password']))){
    // Password verification successful
    $_SESSION['email'] = $row['email'];
    $_SESSION['first_name'] = $row['first_name'];

Remember to bind the entered password ($ctPassword) to the parameter in the prepared statement to ensure secure execution.

Using PDO::FETCH_ASSOC for User Data Retrieval

To retrieve user data more efficiently using PDO::FETCH_ASSOC, you can update your code as follows:

$results = $query->fetch(PDO::FETCH_ASSOC);
if($results && password_verify($ctPassword, $results['password'])) {
    foreach($results as $key => $value) {
        $_SESSION[$key] = $value;
    }
}

This would automatically assign all retrieved values as session variables, making it convenient to access user details on the 'My Account' page.
