Where Should `password_verify` Be Placed in a Login Script for Optimal Security?

Correct Placement of password_verify

In the provided login script, the ideal place to incorporate password_verify is before the if statement that checks whether the queried row exists ($row = $query->fetch()):

if(($row = $query->fetch()) && (password_verify($ctPassword,$row['password']))){

This ensures that the password validation is performed before user information is extracted and session variables are initialized, enhancing security.

Utilizing $results = $stmt->fetch(PDO::FETCH_ASSOC);

The PDO::FETCH_ASSOC method allows you to retrieve data as an associative array, where column names become keys. To utilize this method, you can modify the query execution line as follows:

$results = $query->execute()->fetchAll(PDO::FETCH_ASSOC);

Once you have the results, you can access session variables using the associated keys:

$_SESSION['email'] = $results['email'];
$_SESSION['first_name'] = $results['first_name'];
