How can debugging techniques be effectively used to troubleshoot issues with password verification in PHP scripts?

Issue: When troubleshooting issues with password verification in PHP scripts, it is essential to use debugging techniques such as printing out variables, checking the logic flow, and using error reporting functions to identify and resolve any errors. 

// Example PHP code snippet for debugging password verification issue

// Retrieve user input from a form
$username = $_POST['username'];
$password = $_POST['password'];

// Retrieve the hashed password from the database
$hashed_password = "hashed_password_from_database";

// Verify the password
if(password_verify($password, $hashed_password)) {
    echo "Password verification successful!";
} else {
    echo "Password verification failed!";
}

// Debugging: Print out variables for inspection
echo "Username: " . $username . "<br>";
echo "Password: " . $password . "<br>";
echo "Hashed Password: " . $hashed_password . "<br>";
