How can error handling and debugging techniques be effectively utilized in PHP to troubleshoot password comparison issues?

When troubleshooting password comparison issues in PHP, it is essential to utilize error handling techniques such as try-catch blocks to catch any exceptions that may occur during the comparison process. Additionally, debugging techniques like using var_dump() or print_r() can help inspect the values of variables to identify any discrepancies. 

$password = "password123";
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

$userInput = "password123";

try {
    if (password_verify($userInput, $hashedPassword)) {
        echo "Password match!";
    } else {
        echo "Password does not match!";
    }
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
