How can the use of password_hash and password_verify functions improve password security in PHP applications?

Using the password_hash and password_verify functions in PHP applications can improve password security by securely hashing passwords before storing them in a database and verifying hashed passwords during login attempts. This helps protect user passwords from being exposed in case of a data breach or unauthorized access. 

// Hashing a password before storing it in the database
$password = "mySecurePassword";
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

// Verifying a hashed password during login
$loginPassword = "mySecurePassword";
if (password_verify($loginPassword, $hashedPassword)) {
    // Password is correct
    echo "Login successful!";
} else {
    // Password is incorrect
    echo "Login failed. Please try again.";
}
