How can I securely store and check passwords in a PHP application?

To securely store and check passwords in a PHP application, you should use password hashing functions like password_hash() to securely store passwords in your database and password_verify() to check if a given password matches the hashed password stored in the database. This helps protect user passwords in case of a data breach. 

// Storing a password securely
$password = "mySecurePassword";
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

// Checking a password
$enteredPassword = "mySecurePassword";
if (password_verify($enteredPassword, $hashedPassword)) {
    echo "Password is correct!";
} else {
    echo "Password is incorrect!";
}
